88GMCtruck's never ending 88 GMC build thread

[88GMCtruck]

Time for another build thread! I have enjoyed the other build threads I have kept: the 78 Nomad trailer resto, and the 99 6.5L Towpig. Since the towpig is history, I'm concentrating on the 88 once again. Seeing as I have never kept a running build thread, I have decided it is time to actually make a build thread about my truck to document some of the progress, etc. Plus it's an excuse to post little updates that wouldn't otherwise be reason for a thread themselves.

We'll start with it's history. Grandparents bought the truck in 1988 brand new. It's a regular stepside K1500 350/700R4 truck in top of the line SLE Sierra trim inside and out. An off note, in 1988 the Z71 package didn't exist and the truck for whatever reason did not come with towhooks. What made the truck interesting is the RPO "Super Saver Package" that kept the truck as a SLE Sierra but stripped the interior down to the essentials: basic bench, AM/FM, AC and cruise. No tilt, no PWDL. In 2002 I received the truck with 88k on it (ironci!?).

But it being stock didn't last long.

Being 16 the truck underwent many changes, a good amount of them cheap, free or made up by me being I couldn't afford much. A few were learning experiences, some stayed with the truck, and of course there were a few I am no longer proud of (such as altezza taillights and blue neon).

Due to the miles/age of the truck, I replaced lots of small things, waterpump, radiator, alternator twice, starter a few more times, etc. Eventually larger things like the rear end went out, and a few years later the 700R4 gave up the ghost. By 2005 I was in college and the truck IMO was looking pretty good.

http://i307.photobucket.com/albums/nn305/88gmctruck/88%20Sierra/Old%20Picts/IM000154.jpg

Seeing as I lived in a very snowy climate at college, I also picked up a winter set of wheels that also served as a good wheelin set.
http://i307.photobucket.com/albums/nn305/88gmctruck/88%20Sierra/Old%20Picts/100_0654.jpg

At this point the truck ate through a second 10-bolt and the addition of a 14SF was added. I always was into 4x4ing and my truck, so there was already tons of ideas in my head. Eventually I started making good money in the summers and in 2008 I picked up the 02 GMC. The front suspension in the 88 at this time needed a full overhaul, so about a week after owning the new truck I decided that rebuilding the suspension meant it was time to install a Dana 44 front axle. The parts collection began. A little cut here, a grind over there and a few welds resulted in 3 hard weeks working with my dad as much as humanly possible between work and sleep to convert this thing.

The result was 8" of lift while still being a very streetable, yet capable truck. Build: http://www.fullsizechevy.com/forum/general-discussion/projects-builds-restorations/336282-88gmctrucks-sas-build-thread.html

After a good deal of wheeling and driving later, this happened.

The Automatic didn't like it very much but it survived another 6 months. Then came cablights and stock mirrors sometime in 2009

My previous water incident ended up prompting this upgrade.

The summer of 2010 I bought a 1978 trailer for camping. It's been a project all in it's own. Build: http://www.fullsizechevy.com/forum/general-discussion/tow-haul-mode/441702-1978-nomad-trailer-restoration-project-88gmctruck-again.html After towing it awhile, I finally did a much needed gear upgrade from 3.73s to 4.56s.

The 88 took a year long break from most use when I bought a 99 6.5L K2500 5-speed truck. Build: http://www.fullsizechevy.com/forum/general-discussion/projects-builds-restorations/465678-88gmctrucks-99-6-5l-towpig-slow-build.html

But in the end I sold it and am once again concentrating on this truck. I just finished converting the truck to 8-lug with hubs up front and a detroit locked SRW Corporate 14FF axle from a CUCV.

Next plans include a repower. The stock TBI350 is entirely original and is just about to roll 200k. It burns no oil and has great compression still, just lacking in the power department.

What are those gauge on your dash? Are they some kind of option that these trucks came with?

[daved931]

They look like the altimeter and angle gauge pod my buddy had from the factory in his 4 Runner. I don't believe GM ever offered these.

They are from a japanese spec nissan pathfinder. They fit the dash of these trucks well, and that is it's actual color, not repainted. It had an altimeter I removed and put a transmission temp gauge in it's place.

[88GMCtruck]

Have had a busy week! Lots of things going on at work, and on the project front for me.

Well, the answer to my motor swap came a bit quicker than expected....

Motor came into a friend's junkyard.... 1990 TBI 454 with 76k on it. Motor compression tested 160PSI in all cylinders. It'll be pulled soon and will be going into the 88 in a few weeks. Along with that the transmission is getting a freshening up, and new exhaust will be in the works as well.

I did do a bit of work on it. Saturday I pulled the pinion & carrier and put new bearings in it. Super easy job, had everything apart in 30 mins. :D After re-installing, I gutted the passenger door and put a new door on the truck. Color is a bit more faded, but it's better than dented.

http://i307.photobucket.com/albums/nn305/88gmctruck/88%20Sierra/2012-04-15_21-45-39_685.jpg

Picked it up last Sunday. Well, actually pulled it, but yeah. 1990 Chassis Cab 454 TBI with 76k on it. I even got to drive the donor truck. Looks a little rough, but it was actually spotless inside and the motor was WELL taken care of. Fluids looks proper, and the filters were all wix brand. Here she is. I have the motor with all the accessories, harness, ECM, 34" radiator and shroud.

[88GMCtruck]

Just a bit of an update. Had a party this past weekend, haven't done much in the way of truck work. I have been researching on it though.

Turns out, the motor isn't what I thought it was. Being the truck was a 1990, it has the steel accessory brackets, spreadbore intake and TBI adapter, but should have had stamped steel valve covers.... A 1990 was a Mark IV motor.

The aluminum covers threw me. So after pulling a valve cover, researching the casting numbers on the heads and block it turns out this a a Gen IV L19 service replacement block. Which means it has a good deal less than the 76k miles than the truck actually had. It also explains why the motor was so clean.....

This is not a bad thing. :D Been looking into swapping heads to a smaller chamber to up the compression along with a cam and intake, and some fuel changes. Should put me right around the 400HP mark.

[88GMCtruck]

Started some teardown tonight. Ran the casting number and date code, looks like it was cast February 14, 1996.

Some of the stuff that a Gen V / Gen VI block have. Aluminum valve covers, non-adjustable rockers, unique heads, revised cooling, revised oiling system, dedicated oil cooler ports, one piece rear main, and a 4-bolt main.

Been researching and I think I need to find a set of 96+ Vortec heads.

[88GMCtruck]

No pictures, but I have some news.

I got a killer deal on a never ran takeout roller cam and lifter setup from a vortec motor. $115. I could not pass that up. All the hardware to make this a roller. Then found never ran GMPP Mercruiser cam for $35. Picked up ARP head bolts for $45 and a GMPP zz502 timing set for $48.

So the plan is now run the mercruiser roller cam, it looks like it will pair nicely with the powerband I want. The mercruiser motors made a good deal over 300HP with vortec heads. I found a few sets just haven't pulled the trigger on them yet. Sort of waiting on funds at the moment.

[88GMCtruck]

Received the GMPP timing set and ARP head studs today. My dad is giving me a Edelbrock Performer RPM dual plane manifold, so that will save a few $$. Have a few other parts to get ordered up, gaskets, heads, TBI rebuild kit, and TBI adapter.

This weekend the truck is getting the motor and trans pulled. Trans needs a rebuild while we are at it.

[88GMCtruck]

Welp, didn't get quite enough motivation to pull the motor and trans, I did however do a bunch of other stuff.

Dad gave me an Edelbrock Performer RPM manifold he had. It's a squarebore so I ordered an adapter for it. Overall cheaper than buying a manifold outright.
http://i307.photobucket.com/albums/nn305/88gmctruck/2012-05-19_14-27-16_416.jpg

Yesterday I pulled the heads and dis-assembled the TBI, and today I spent the afternoon sandblasting lots of parts and pieces. After pulling the heads, then cleaning.

While I was cleaning, Dad decided to remove the lump from the emissions ports. Figured since I'm running the manifolds they should flow somewhat decently.

[Solid94]

Looks to be coming along good! I'm jealous that you will have a 454 in the truck. I'm in the same boat as you, the TBI 350 I have runs fine and has good compression and all, but not the power I need/want. I will need to research like you a way to change that. Keep up the good work and I can't wait to see how this build turns out!

[Big2500Red]

Very nice build! I always likes this truck

[88GMCtruck]

Another batch of parts arrived!

Factory take out Gen VI 454 Roller setup. I won't be running this cam, it's a stock L29 Vortec cam.

one luckky man to get all these deals hah xant wait to see the final product

[88GMCtruck]

Still waiting on the heads to show up next week, so i'm trying to get all the little details worked out now while i have time. One of the details that has been driving me crazy is the passenger side accessory bracket. The donor was a non-A/C truck so it had a dummy pulley. I'm going to retain A/C in my truck. I've been searching for weeks to try and find a bracket locally (or one online cheap) and haven't had much luck. In my searches I did find this
http://www.kwikperf.com/sitebuilder/images/plates_engine_talldeck-265x198.jpg

Adapters from Kwik Performance. They utilize the aluminum 2-piece brackets GM used on 90-94 smallblock and V6 motors. After being unable to find the 454 bracket, I went to the junkyard and snagged up these.

http://i307.photobucket.com/albums/nn305/88gmctruck/2012-05-25_22-05-26_775.jpg

The right one is driver's side alternator and power steering pump bracket. The two left are different variations of the passenger side bracket. The middle is A/C only, left is A/C and Smog pump. Why on earth did I buy a smog pump bracket?

No, i'm not running a smog pump. It is the perfect location for a second alternator. After thinking about it and considering I have a spare, I figured why not? It will be isolated from the main electrical system. The idea is it will run a few accessories, primarily a 110V inverter, and be wired to charge the trailer while driving. The inverter will be able to power tools and such, as well as a 110V air compressor that I have.

http://i307.photobucket.com/albums/nn305/88gmctruck/2012-05-26_02-12-27_63.jpg

Took a bit of grinding and cutting, but here is the result. I'm not 100% sold on it's position yet, as there is another alternator clocking out there that might look better?!

Goals this week are to finish sand blasting/painting parts for prep, clean up the engine bay, figure out the wiring harness and rebuild the NV4500.

By you adding that adapter to your 4barrel manifold and putting on your tbi will it still function the same?

[88GMCtruck]

Yeah it'll function just fine.

[kiing23]

Do you have a picture of it on your motor yet?

[88GMCtruck]

I'm waiting on my heads to show up still.

[sdillinger]

Instead of a 2nd alternator did you consider an engine driven air compressor?

[88GMCtruck]

Never.

Ok that was sarcasm :P Only reason i'm going this route is because it really isn't costing me anything additional and it will be more versatile this way as opposed to a compressor.

[Chriscon7]

This build is so awesome!

[Benny00Z71]

This build is so awesome!

agreed! Sub'd

[Solid94]

Nice work man. This is another anticipating build to watch

[hillbillybowtie]

Im back from a loonngg hiatus to subb to this thread. Awesome. Your the reason behind my nv4500 swap in my '80.

[88GMCtruck]

Thanks guys, glad to have interest in the swap from fellow GM gearheads.

The NV4500 is a great trans, isn't it?! Gotta love the gearing in that beast.

------------------------------

So, last week I received more parts.... And one was missing. Turns out the head company didn't ship one of my heads. So I'm waiting on that. No huge deal, still had more things left to do.

End of the week I started cleaning up and painting things.

Finally some HP for this truck!! Looks great, but I've come to expect that from you haha! I especially like the gmc badge on the valve cover, perfect touch. So did the missing head come in? Did you fire it up?!

Head showed up and was on, everything is together now.

--------------

That... was... a... long... weekend. *thuds*

Short story: The motor is in.

Long story (photos): Spent all friday night installing the second head, valve covers, intake, plug wires, etc. Saturday was installing the manifolds, accessories, cleaning the engine bay and rebuilding the 350 wiring harness to work with the 454. Sunday, everything came together. Tonight I got it fired up after dealing with minor fuel and timing adjustments.

I've got it running, set the base timing and that is about it. The 3-wire oxygen sensor heats up quickly and the truck goes close loop, thinks it's running lean since as the sensor is RIGHT next to the open manifold. Next step is to find a way to get it to my parents house to get the exhaust welded up.

[BAD '90]

Looks factory in there!

[hillbillybowtie]

Looks awesome man, Great job. Did you see a noticeable sag in your front springs between the small block and the big block?

[88GMCtruck]

I actually didn't notice a difference if there even was one.

[Spuradik]

damn lookin good! I got an 88 same color... Actually in the middle of a complete build myself, waiting on all my top end parts to arrive so I can slap it together, but I'm keeping the 350. Also gutting out the interior and switching to a 98 interior with a 2000+ cluster. was actually about to drop a duramax 6600 in it but the deal I had on it went south...
once I'm all done I'll post all the pictures and info up for everyone.

http://i307.photobucket.com/albums/nn305/88gmctruck/2012-06-12_22-56-08_78.jpg

3" 409 Stainless True Dual exhaust with stainless Magnaflow XL mufflers. Took a day to get it fit together, but it's in. It's loud. Much louder than I expected. It sounds like a musclecar... definitely a big block rumble. It is quieter in the cab though. I think my neighbors might not like it much, particularly at 5AM.

I've also gotten the data logging up and running using winALDL and am working on getting it tuned. As of now it's running rich at idle and lean at WOT. It also idles WAY too high but that should be fixed soon.












And yes, that is a tail under my bumper.

[hillbillybowtie]

We need videos ASAP man. Exhaust looks great, whos kit is that?

[Iang]

X2 on the video. I believe it's Flowmasters U-Fit kit.

Yup, it's the Flowmaster U-fit kit. Got a good deal on it. And i'm working on the video, I have some I just need to pull off the phone and upload them.

[88GMCtruck]

Alrighty, here is an idle video. Once I get more tuning done i'll have to get another video together.

That thing is baller dude! Hate to be needy, but can we get a video of you rowin threw the gears? Just trying to get a handle on the power it makes.

I will eventually. Want to get it tuned up first.

[JAYB1RD]

Sounds healthy, love the pipes, screw the neighbors haha!! Maybe I overlooked it, thought it was left stock, but did you change the cam?

[Solid94]

Great work bro! The engine bay looks very clean. Sounds like my 71 Chevy. It has a mild cam because we turned it into a dump truck. Definitely sounds mean. Do you have a video with a little throttle?

[88GMCtruck]

Sounds healthy, love the pipes, screw the neighbors haha!! Maybe I overlooked it, thought it was left stock, but did you change the cam?
it is definitely not stock. The bottom end is original with flat top pistons, and I put vortec heads (upped the compression and larger ports), mercruiser cam, converted it to roller,and have the intake and tbi was modded running 18psi and a 115lph pump.

Working on it. I want to get the tune dialed in first.

[JAYB1RD]

Very nice! That should make for a real fun ride and something you can build off of in the future too. Good luck with the tuning, I just started playing with my laptop and cable too.

[BAD '90]

Sounds great man!!

[88GMCtruck]

Not a ton of news surrounding the truck. Been mostly fine tuning things and working on the trailer project. I was having an odd intermittent idle issue, after a bunch of adjusting and checking, I ended up replacing the Idle Air Control Valve, and after the most recent datalog and chip it's really getting dialed in.

I FINALLY got airbag installed on the truck. I've had them (they were on here long ago and were on the 99 diesel as well) and just hadn't got around to building something that I could use with the truck. So i don't rip them up I made a removable "leg" so to speak that makes up the space between the axle due to the lift, and will allow them to be disconnected when i'm not towing the trailer.

Excuse the lack of paint, I haven't gotten around to spraying some on it yet.
http://i307.photobucket.com/albums/nn305/88gmctruck/2012-06-30_20-53-26_420.jpg

I also finally got a new spare for the truck too, just a stock steel wheel and a worn out 315/75r16 bfg a/t

[Solid94]

Nice work bro! Do you like how the Firestone kit works? Or have you not gotten the chance to test it yet?

[Blue 04 Z71]

[88GMCtruck]

Nice work bro! Do you like how the Firestone kit works? Or have you not gotten the chance to test it yet?
Well, I've had this kit for YEARS. It was on this truck way back when before the SAS, then put them on my 99 Diesel with a tank and compressor, now they are back on here. It's a specific set for this truck, fits well. I installed the spacer when I was modding the trailer tongue so I towed it home with the bags inflated.... If you've never used them your missing out, make the ride so much nicer.

I've put a lot of money into this truck, I don't think it will ever end. Contemplating upgrading to the newer dash and grey interior at some point.

[Solid94]

I will have to see the work and pics if you update the dash. I'd like to do it too but I heard its a lot of wiring. But if you do it I know it will look good. Everything else you have done has been cherry

[Andy H]

Nice work! I use to have an 88 sierra and an 88 cheyenne. I wish I still had the sierra!

[88GMCtruck]

Well, here is the latest on the truck's front.

Bought new hitch, it's a drawtite 16k forged 6" drop.
http://i307.photobucket.com/albums/nn305/88gmctruck/2012-07-09_17-05-03_339.jpg

Fixed a bunch of small things that I've put off, and gave the truck a full wash, wax, vac and upholstery cleaning. First time since around November! Not bad for 24 years.
http://i307.photobucket.com/albums/nn305/88gmctruck/2012-07-10_00-31-43_302.jpg

I then got the quads in the truck, trailer loaded and everything hooked together.

Truck ran great. It pulls, so much torque. I had no problem keeping speed everywhere.... At least for the first two hours. At some point it started hesitating, coughing and would give me no power.... So I pulled over and swapped back to the last chip. It ran fine a few more miles then again did was running poorly. Pulled off, multimetered a few sensors, checked connections etc, and hooked the laptop up. Ran fine a few miles, then again it started acting up. So, over on the side of the road again. After a bit of a cooldown period (for me) the data was looked at and it looked as if the oxygen sensor (which was new) was reading high voltage, above the norm which indicated it was likely failing, and making the truck think it was running rich, thus cutting fuel. being it was now about 11PM, I was in the middle of BFE and had 4+ hours of driving left, I unplugged the sensor and ran with the base fuel map and the SES light on. Truck ran without major issue after, unfortunately netting me about 5.5MPG...... But I made it. Next morning a stop at Napa and a new sensor was installed and it ran great after.


Here is the sand camp. All my toys in one spot!
http://i307.photobucket.com/albums/nn305/88gmctruck/Oregon%20Dunes/2012-07-14_19-30-45_205.jpg

Packed up, heading home. Running properly, I netted about 8.1MPG doing about 70MPH most of the way.

What a nightmare and pain in the ass! Glad the truck is running good again. Definitely looked like a fun trip!

[JAYB1RD]

Sweet pics! Cant wait to get my truck back on the sand, thanks for the extra motivation! The bikes, trailer, and truck are all full of retro win :)

I need those tow mirrors, and a vid of said 6k rpm big block goodness haha

[chevychris]

wow!!

awesome looking truck!!!

[88GMCtruck]

FINALLY got photobucket to cooperate, here is 2 short clips from the sand. These are low range, 4wd runs. Used 3rd and 4th.

I am going to be looking at installing my 34-gallon Longbed tank in the near future. It's going to take a we bit of modification to get it to fit...

Finally getting the truck's tune dialed in. It's really running great.

Few weeks ago made another trip down to the dunes. Managed to fit 2 quads in this time with the toolbox in the bed.

Managed 9.2 MPG towing this setup doing 70-75 MPH. Was a great trip.

Going to be some slow progress for awhile, working on saving for a house and going to try making it out camping this fall/winter some more.

I show these pictures to all the Regbox Stepside haters, awesome load job. Small box but you can fit lots haha!!! You have the nicest truck on the forum by far too, great job!!

[88GMCtruck]

Thanks! It's always been a challenge with the small configuration. Nothing creativity can't overcome.

Took another trip camping awhile back, was out in the snow/rain so I threw the canopy on the ol' girl. Haven't seen that in awhile.

Other than that, not much to report. Truck's running well. Detroit locker is a chore in the wet winter weather. I recently was having speedometer and RWAL issues, my speedometer sensor was bad (go figure) and messing with both systems.

Very soon I'll be looking at tires. These ones are about at the end of their useable life for me, they aren't going to do very well in snow or mud this year...

[88GMCtruck]

Had to lock the hubs in this weekend. Decided to find some snow over the weekend. Didn't get much but it rained previously, so it was a bit slick to drive around on, and the roads on the way home were snow/slush mix. Freeway speeds in that crap with the trailer is fun :P

88 got a christmas present this year. Weathertech floor mats. I've had them in my 02 for quite some time, yet they have never listed them for a GMT400 truck. I more recently found out they list them for 92-99 suburbans... So figuring the floorpan is the same I ended up with a set. They are to replace the husky liners I had before.

I am a sucker for a painted full floater flange through the wheel though. Just says beef.

Yeah, I should say "wheel". I only did one before going to dinner to see if everything jived together. I have to drill the fronts for the hubs still, and will get them all on and get full pictures for you guys.

I really like my socket lug setup because I think they just look mean, and help show off it's 8-lug. The OEM caps are more finished looking, and definitely make the 8-lug swap more subtle.

Fronts & rears now

It definitely makes a difference to see them from an overall shot as opposed to close up

Quick little mod. I used to have "SS-350" door emblems on the truck. When I swapped the 454 in I went back to the "GMC1500" originals. Well I recently picked up a set of "454-SS" emblems. I want something that helps indicate it's not your average 350 powered pickup a little moreso.

I do wish they were all silver like my "SS-350" emblems were. I'm also toying with the idea of hacking these and my "GMC1500" emblems up to say "454GMC".

Whats this?

^^wow!!! great find!!

[88chevyshort]

I absolutely love your truck. My favorite GMT400 by far. I cant wait for the day I can start putting money into mine again. for now shes off to the side without a motor =/

[Solid94]

Was something wrong with your current bed sides?

[88GMCtruck]

One has a large crack in the wheelwell, and both are de-laminating in places. Seemed easier to just replace with a clean set than try to repair.

So is a full repaint in the future?

Future, not the immediate future though. Still need another tow rig and a house. All in good time.

Oh okay. Yea I did the same with my hood. Was peeling. Figured $75 for a hood from a wrecked 96 was cheaper than to repaint mine

And BTW your truck would look good black if you decided to paint it that color

[88GMCtruck]

Ok, I finally got off my lazy bum and cleaned, painted and installed the XJ shaft. While I had the original shaft out I also re-set (tightened) the steering box pre-load, and adjusted the over center.

http://i307.photobucket.com/albums/nn305/88gmctruck/IMAG0854.jpg

Truck has much better steering once again. Much more responsive. It still feels like it's on balloons (35s) but there is no way around that.....

[1998regcab]

What exactly does the XJ shaft do? I've heard of the swap but never understood the point of it.

Does it just bolt right in?

[88GMCtruck]

Basically. You have to file a small spot to get the bolt through on the column side. There is a thread on it somewhere.

Not sure if that will work in my truck. Dam, oh well.

Installed a new Delco fuel cap with tether. I had my original cap from 88 still. About a month ago I was helping a friend move, ended up loosing the cap at the gas station (was more concerned with the snow on the pass and a clean windshield). So, I replaced it with another OEM cap from the boneyard, ended up loosing it on my last camping trip...... So ended up getting this year correct cap with tether.

looks like a lot of fun.

[JAYB1RD]

Does your gas door not have a hook built into it? I always hang my cap right there inside the door, I don't even think you could close the door while it's there?

[5speed_93_Z]

I dont mean to interfere with this build thread but i couldn't help but notice you converted your over to a straight shift i was wondering if you could give me a few pointers on the conversion I'm doing the same i have all the parts just haven't pulled them off the parts truck just yet waiting for some advice and pointers lol
