very disappointed in memphis

[98_vortec]

I TOOK MY 98 RCSB TO THE TRACK AND IT RAN A 16.93@80.22MPH. :damnit: DOES ANYBODY KNOW WHAT THESE TRUCKS USUALLY RUN ITS ALL STOCK EXCEPT A HOOKER AEROCHAMBER MUFFLER. I'M DISAPPOINTED CUZ MY 90 RCSB RAN 16.4X @ 88MPH AND I THOUGHT I WAS UPGRADIN MY PERFORMANCE MAYBE IT CUZ THE 98 IS A 305 AND THE 90 WAS 350 TBI ANY INPUT

[Sbc_inside]

Im no doctor....but the cubic inchs will make a difference. Im not sure on the HP difference between the TBI and the vortec, but im sure its not all that much.

There are all kinds of things you can do to make it run faster if you want. Do some searching around here and you will find all kinds of good info. I mean hell man....it is just a stock truck after all.

[98_vortec]

I know its stock but i guess i was expecting better times from my 98 than my 90 due to a smaller but more powerful motor

[bad2006z71]

the vortec 305 was 210hp and 290lb ft of torque, the tbi 350 is 220hp and 330lb ft of torque.

the vortecs power band is slightly higher than the tbi's i believe. vortecs also had TM in them though not as much as the Gen III stuff.

did both trucks have the same gearing, tire size? that could make a difference also.

Is it in good running order? Fresh fuel filter, air filter, distributor cap, rotor, and plugs can really liven things up if they are in need of replacement.

never really checked all of that these things are now on my to do list.

[the_husk]

The vortec 305 has slightly less power and torque than the TBI 350. That is your problem right there.

[98_vortec]

never really knew the specs guess i should of done my homework but all in all its a damn good truck and i love it it has a 305 with a 3.42 but its not posi my 90 was a 350 with unknown gear

[the_husk]

I'm not saying it's a bad truck. I'm sure it's a great truck. I know I LOVE my 5.7 vortec.

You might add 4.10's and a S-10 torque converter and watch those times dip down.

[1988 GMC 355]

The tbi 350 is 210 hp and 300ft.lbs of TQ not what is stated above but a tbi 350 has a more TQ than a vortec 305 and lower in the powerband

[Pauly]

Vortec 305 makes 230hp and 285 lb/ft torque
TBI 350 200-210hp 300 lb/ft torque


]My stock rcsb Vortec 350 with 3.08 gear ran 15.7-15.9 in teh 1/4 mile.

peace

that good my pop 04 gmc with a 5.3 3.42 ran a 16.6x @ 88.xx

Yep EASILY...My Express van with the L31/4L60E/3.42 STOCK ran a 16.8 @ 84.5 in the 1/4.

Here we go again.:LOL::rolleyes:

[1988 GMC 355]

I dont think he will get tired of posting about it though.:banghead:

[bruno]

My 1996 RCLB with a 305 ran 16.20's @ 85 But the 60' was a horrible 2.7.... No traction what so ever.

If that helps any.

[Outlawz2004]

I drove a 95 TBI 350 today, what a joke. Never drove one before and expected more after hearing all this talk about how much torque they had.LOL. Barely would spin the tire 5 feet, this one had 60,000 miles on it. I was going to buy it until I drove it,lol. My 4.8 would kill this thing when it was stock. My 98 vortec 350 definetly had a lot more balls than this thing.Sorry if its a little off topic, but I know my friends vortec 305 has more get up then the truck I drove today. Must be the gearing.

[the_husk]

I might have a 98 rcss for sale...all the 5.7 vortec you can get lol.


As for the thread, Mine went 15.666 stock with a decent exhaust. Good number eh?

Nice, you ended up getting down to a 13.9 didn't you?

[StreetFreak]

Nah. It does 14.7s now on a stock tune and with no rings whatsoever lol. New motor is in the shop just gotta settle on an intake.

Yeah I used to have 4.10s in it along with a minispool and drag radials. It did 14.39 on a g-tech with that setup.

Current is 3.42 open diff, shortys, magnaflow muffler (no cats), ported tb with lip removed, aeromotive a1000 fuel pump w/ stock injectors, s10 stall, shift kit, and a custom cai, prolly a few other little things i dont remember but nothing major.

Ah, I have a 96 Z-71 that has CAI, longtubes, 2.5"true duals from collectors back to cherry bomb extreme mufflers, 3.73's, and a few other odds and ends. I REALLY picked up some power by switching out the stock headpipes. It moves out really good now. I'm fixing to do the marine intake swap, as I have one on hand, and an agressive custom tune for those mods, along with a 2800rpm stall converter with 2.0str.

Nice. When I go with longtubes I'm gonna make a better y-pipe for it. I really want to do a marine intake but they all cost exactly one million dollars around here.

Actually your still wrong. :lol: j/k

In 95 the L05 TBI was making 200HP/310 ft.lbs to the Flywheel:D
The L03 305 was pushing 175HP/265 ft.lbs

In 96 The L31 Vortec 350 was making 250HP/335 ft. lbs to the Flywheel
The 96 L30 305 vortec was 220HP/285 ft lbs.

An old aricle straight out of Apri '96 chevy truckin' magazine. They compare the 305/350/454 vortecs to the 95 TBI engines 305/350/7.4. dont get more legit then that

Wow you drove a bad truck then.

My 350 TBI truck in sig with 420,000+ miles on it will still outrun my Uncle's 98 RCSB 4.3vtec, same gearing and mines a 5 speed. Him and my dad ran on his 1/8 mile long driveway.

My neighbor had a 2001 ECSB z71 with 4.10's, 33's and a 4.8 and he hated it, Had no balls and would barely do a burnout.

He sold it for 8g's and bought a 94 ECSB 2wd 350/700r4/3.42 truck and loves it, says it would run circles around his old 4.8 truck. Loves the torque and it lays rubber when you just floor it froma stop.

Whats awesome about the TBI's is they are more reliable than a Vortec engine and thats a fact. And also is cheap to mod them. I added about +5 on the driveability scale on my dad's 87 305 tbi truck with 2.73's and a700r. Just did the FREE ultimate tbi mods, a $30 throttle body spacer, and a $10 inj. pod spacer < best mods you can do to a tbi. along with a cherry bomb vortex muffler and a k&n filter the truck scoots now and lays a one wheel peel if you mash it from a stop.

You drove 1 tbi truck and now you give up?? What body type was the truck and what gearing?? how do you know the air filter wasn't clogged or something mechanicly wrong??? You must drive a vette everyday to think a TBI 350 truck has no torque considering its age and how behind its time it was. With less than a $100 TBI trucks run pretty damn good. I'd know because my dad has owned about 3 of them in the last 5 years and all were 350 trucks and ran 15's in the 1/4 with minimal work.

My Dad's 92 RCLB 2wd with a 350tbi,700r4,3.42's, jet 6 pos.chip, tb spacer, k&n air intake, flowmaster muffler ran a 15.56

My dad sold that and bought a 97 ECSB 2wd, auto, 3.73's, 350 vortec, hypertech programmer, 15.34

My dad sold that POS vortec truck,bought another tbi truck was a 92 RCSB 2wd,350tbi,700r4,3.42,jet 6 pos. chip, K&n filter, Flowmaster Cat back, 15.3 all these times are at sea level BTW

At 74,000 miles the SCPI spider cobweb bull**** was messing up on the 350 and it would barely start hot or cold. Turned out to be some $379 + labor regulator under the friggin intake . Sold it after that issue. along with all the other problems he had with the truck itself. Bought a 95 2wd cummins, made it run 14's

[crossy's son]

Ditch a TBI trucks ****ty intake setup (baffle) and ditch the facory 2.25" y pipe and add a good exhaust and they don't run that bad. Top end power can't be helped because of the 193 heads.

I don't wanna be an a-hole saying vortecs are junk and tbi's are the best becuase they're not. TBI's and VORTECS both have their weaknesses and strong points.

[crossy's son]

brandon, where can i get a copy of that article?

Not sure, it was in a box in my basement. My dad always kept cool stuff like that. he's got lots of neat articles.

[CarolinaHD]

yeaa soo bout that artcle lol....

edit: nvm haha

[FordeatinZ71]

:word: Brandon. very well put.

:word: Brandon. very well put.

you, get focused there are bigger things that need to happen lol

[crossy's son]

I'm sorry its actually from the April '96 issue of Chevy truckin magazine.

I was getting confused with another article on my desk, on how to port vortecs.

[CarolinaHD]

sounds like its worth readin, might have to go look it up

[FordeatinZ71]

you, get focused there are bigger things that need to happen lol

lol, like what? the TBI swap is done. check the other thread. i posted a video there just now :cool:

[CarolinaHD]

currently watchin it on chat and she just started up :thumbup:

good work my friend

[FordeatinZ71]

haha thanks man! i know it's not a Vortec or anything...but i'm happy...:lol:

[rebelbowtie]

My neighbor had a 2001 ECSB z71 with 4.10's, 33's and a 4.8 and he hated it, Had no balls and would barely do a burnout.
:lol: :lol: :lol: just because it couldnt do a burnout means its got no balls? my old 4.3 i used to have could smoke the tires on 33s. and i had a ford ranger with a 302 that would smoke the tires on 35s in multiple gears(stick). and my 92 tbi 305 will spin its 33" tires too. does that make any of those trucks powerful? nope. kirks 4.3 will spin his 39.5 iroks doesnt make it powerful. just because a vehicle will spin the tires doesnt mean it has alot of power or torque. my 6.0 barely spins my km2 so i guess i should sell my 6.0 and drop in a tbi 350 or 305 since they can spin the tires better. your logic is ****ed

come on now, the tbi & vortec 350's are king/god, nothing can nor will ever be able to touch them, outrun them, out tow them, get better mpg than them, or last as many miles as them. you have a slow truck, if it had a 350 in it it would be fast and powerful. :happy:

[StreetFreak]

Hey now as long as the vortec 350 is in something that wieghs as much as a piece of toast it will haul arse.

As far a reliability...seriously? My truck MOTOR has survived 150k of hard ass miles including countless WOT runs and even a few balls out top speed runs. The only time it ever had ANY problems was when I put a 150 wet shot in it and a melted piston was the result. To the op, Do some simple mods (remove the throttle body blade lip, some shortys, and a good ignition tuneup) and you'll stomp all over the tbi350's times.

your head is msssed up because i said no balls AND would barely spin the tires. If you simply floored the truck from a stop it just made a bunch of noise and went nowhere. It simply didn't have enough bottom end torque to move such a big truck.

If you would of read what i said and not skimmed through it you would see that everything i said came from experience. I don't make **** up and talk ****. Hell i even said that both engines have their weaknesses.

one reason your 6.0 won't do as good of a burnout because it has rear disc brakes.

Now the 2000 RCLB w/t 4.8 my dad drives to work has good power but it weighs nothing compared to most trucks because its a w/t.

Hey...i'm tired of you ragging on the 4.8L :argue:

I know its small but it gets the job done....
:looking:

[Outlawz2004]

You must drive a vette everyday to think a TBI 350 truck has no torque considering its age and how behind its time it was. all were 350 trucks and ran 15's in the 1/4 with minimal work.


I drive a 4.8L ext cab with intake tune and exhaust that runs 14s most days of the week, and the rest of the time I drive my mustang with full bolt ons. The dude drove my car and he said"damn this thing has some balls, I cant believe we are already at 70 mph." The TBI was gutless, my 98 350 vortec 2500 4x4 I sold would smash this thing in every way. Yes, I know this is one truck, but as your examples stated, you are comparing your experience with single trucks. This truck was perfect mechanically, we inspected the thing inside and out before the test drive. The dude kept saying feel how much torque it has, and I just kept waiting for it to come on, but never felt it even remotely pull me back in the seat. As I stated, weak as hell.:smokin:

[GreaseDog]

Im no doctor....but the cubic inchs will make a difference. Im not sure on the HP difference between the TBI and the vortec, but im sure its not all that much. probably has more to do with the flow in the runners in the head, and the small bore shrouding the valves than anything. that's the big drawback of the 305, otherwise its a great little powerplant. dead reliable, and makes reasonable horsepower and torque. good daily driver stuff, not so great if you're looking for speed.

[GreaseDog]

dang well I was close, I'll blame it on dislexia!!

[1988 GMC 355]

And I love my tbi truck and will always have them since they are cheap to mod and cheap and easy to work on and since I will be in college if something happens I can probably fix it.

My new truck weights 5200lbs with me and 22 gallons of gas and it puts me back in the seat,no problem. My buddies say how impressed they are with the way it pulls. The most expensive thing I have done was my exhaust and everything else only cost under $100

see, i had a TB spacer on my '90 C1500 (ECSB with a 5-speed and a 350) and it felt like it LOST power. it just made more noise. but i'm thinking about doing the TB and pod spacer on the Blazer...give it one more shot in the saddle.

Do both spacers at the same time, Then do the ultimate tbi mods (http://www.tbichips.com/ultimateMODS.htm) and Put a quarter inside your fuel pressure regulator (If you can handle that PITA task) and your blazer will pop a wheelie.

[FordeatinZ71]

haha, maybe with some real gears in it. WTF made GM think 2.73s were a GOOD idea in a K5 with a 305 and a OD trans? at least this one didn't have the factory 31" tires my "like-drivetrained" 83 K1500 did.

[5.7L JWL]

I really want to know what mine will do with the few bolt-ons I have. I'd hate to break at a track with no way home.
