Would this be a good kit for my Truck she has 5.7 vortec with 6in lift with 35' im ordering us standerd 4.56 for my truck just wonder if this would be a nice set up for my truck?

[6789olds]

http://www.summitracing.com/checkout/cart.aspx i like this set up

[speedracer326]

That's a flat tappet cam, your Vortec has a roller cam.

[TheDuke90]

Y cant i go with the flat tap? cause the kit come with the lifters cam everything to run flat tap is that a bad idea?

[TheDuke90]

wut about this? Olds ur post of summit didnt work

[speedracer326]

It worked fine, but for me it showed Mustang shorty headers. Why would you want a flat tappet kit when your truck already has roller lifters? The roller lifters simply get reused, they don't mushroom like flat tappets. You can get cam and springs and be good. It's like putting a carb on your truck, it'd be a downgrade. No matter what cam you get, you're going to need a tune. Have you considered that?

Edit: check out this one http://www.summitracing.com/parts/CRO-00462/ Hell, that looks appealing to me.

i posted a zz4 cam with comp springs 26918 and comp 787 retainers .

[TheDuke90]

Alright i gotch ya I'm a fan of comp cam thats wut I run in my camaro in my 67 Impala, just new with the whole vortec set up so I really just need get a Cam and Springs and retainers then? theres no point of running new lifters?

After i get my cam set up and headers then im going take my truck in to get tune im not going buy programer to me those are waste of money espical after getting a custom tune you get so much more power!!!

http://www.summitracing.com/parts/CCA-08-413-8/ with this cam its a .474/.474 lift do i need replace springs and all that? should I replace the rockers on my truck with some 1.6 alum?

personally I think you are at least 1 size too big with that cam for a 350. You're pulling 35's and will need all the torque you can get down low. There's a member on here MGrotel or something like that selling his 411-8 which is one size smaller than the one you posted. I have the 409-8 and am very happy.

[TheDuke90]

so many choices lol why you think that the cam i post wont give me the power i need?? cause I got 4.56 gears on this truck.

Thank you everyone thats been helping me I love this website you always get good infor and dont deal with pricks!!

[93ChevyTBI]

you always get good infor and dont deal with pricks!!

you'll get power out of it for sure on top end but lose on the bottom. If you're ok with that, so be it. But you're running a big heavy lifted truck and really need the torque. Run a simulation on it and see where your power is. I've got it on my old computer....all 3 of them as well as 3 of the voodoo series.

As for your last comment, oh, they're out there, sure enough. It's just takes a little while for some to come out of the woodwork lol. Most 98% of us here are pretty good guys and then there's the other 2%.....just like anywhere else.

[TheDuke90]

Alright man so ur saying with the smaller lift and lower rpm cam be quricker off the go?

[93ChevyTBI]

Alright man so ur saying with the smaller lift and lower rpm cam be quricker off the go?

ya but actually it's the duration that makes it quicker off the line. You want as low duration as you can manage with high lift. I had a 212/218 in mine that ran like a bat out of hell on top but not so good down low. And the biggie for me is I don't ever stomp on it like that hardly so what was the point? I also went back to a stock converter which was much appreciated...lesson learned there. I don't like having a higher stall at all but that's just personal preference. MGrotel had the 411-8 in his 383 on a lifted truck. You were wanting to put a bigger cam with a smaller 350 in a similar truck......wouldn't be a fun drive.

[TheDuke90]

alright I understand what your saying now so could you post a cam from summit for me that you think would be great for my truck? I'm a heavy foot i know there not ment to be drag truck or nothing but if some high school kid pull up in a gtp start messing with me want be able to at least pull away from him off the line u know wut I mean?

http://www.summitracing.com/parts/CCA-12-412-8/

[93ChevyTBI]

you'll need head work with that cam going over .480 (springs), probably higher stall (desired but maybe not necessary). The biggest thing that caught my eye was the LSA of 110 degrees. I don't know how Vortec injection responds to that low LSA...stock was 111 as is mine and the 08-411-8. You would either have to ask Comp or a tuner how it responds to the lower LSA. Personally I'd like to try the 411-8 but would have hated not liking it and swapping out so I went one size lower.

I think they have a line of roller Voodoo cams...always worth a look on them.

[speedracer326]

Higher stall will cook the trans, especially if he offroads since he's got a lift and tires. The cam I posted above has less duration than the one you posted. The one you posted is for a non-roller block, it's a retro-fit cam. LSA's might be a little low on them, but since you're going to get it tuned anyway I don't see why that'd be an isue (from a tuning standpoint). Perhaps a cam guru could chime in on how it would affect the low end torque.

[SUBURBIAN]

Shorter duration equals earlier intake closing event. This is the majority of what makes cylinder pressure (power). It also allows an engine to "run out of breath" too soon if it is too short..

It is about the balance...just enough and not too much, based on a snapshot of the entire setup and intended use.

[93ChevyTBI]

a moderate stall like an s10 stall will not cook the tranny....it's just not ideal when climbing rock ledges. Trust me, I know this...that's why I took mine back out. It's like a bunch of small jumps over the ledges instead of crawling

[mattoo18]

Sorry to threadjack, but how would Comp Cams 08-409-8 effect my mpgs? How about an s10 or trailblazer torque convertor? I have heard that the TC wakes the truck up but I cant afford to hurt my mpg's at all. Im getting 10.2 in town.

mehhhh, I don't think it has really done anything to my mileage but it's hard to say b/c b/c I also changed from S10 converter back to stock. I get around 13 highway 11 in town. S10 converter will hurt it...I think I gained 1 mpg back going back to stock. ...a friend of mine says it cost him 2 mpg. If you have a torque cam/set up, your truck won't need the wake up

[TheDuke90]

I'm looking at the comp cam 08-411-8 do i have do the new spings with that cam or any other swap?

[93ChevyTBI]

"supposed" to always change springs with a higher lift cam.....I didn't but mine is just .458/.458. That .474 will be stretching it as some experts say max lift on vortecs is .450 or .460. I just went with what the majority said at .480...so .474 is a gamble no matter which one is correect.

[mattoo18]

So, if I get a torquey/low end power cam I shouldnt need a new tc? I dont run my truck hard because I cant afford it, so I would like to have a cam that helps on low end more than up high. Also, would I have to do any head work if I get a cam?

Thanks

Matt

[93ChevyTBI]

Nope...not at all....assuming you are geared correctly or close to it anyway. I'm pushing 440 ft/lbs at 2000 rpm (lowest DD would go) almost so I have no need for a higher stall whatsoever. After the cam swap from my 212/218 cam, it was stalling way too much for my likeing.

I have the 08-409-8 and freaking love it. I can drive it daily with no issues with stock stall. I can tow and have no worries. I can get on it to have some fun. And you know what.....if it runs out of breath after 5000 or 5200, I don't care b/c I very rarely do that....maybe 3 times a year.

You have a 97 so it would be a very easy swap for you.....just the cam. Most people would say springs too but that's your call.

[mattoo18]

Awesome thanks. Would springs be worth the coin for them. My motor is stock. I will be installing headers soon. This cam wont hurt my mileage and or drivability will it?

Thanks,

Matt

[93ChevyTBI]

headers will only help it that much more.

I think you can get springs pretty cheap...the Z28 springs were very cheap..can't remember...like $30 or so and they will accomodate up to .525 lift I believe....don't quote me on the price

[mattoo18]

Where did you find springs for $30? I am definitely not opposed to spending a little money for better perfomance but I know nothing about the spring and all the different choices.

Also, is Summit my best bet for prices on the cams and springs? Im a college kid looking for better performance on a tight budget.

Thanks,

Matt

[TheDuke90]

Do you think with the comp cam 08-411-8 would be a good cam for a everyday driver? cause this truck is my everyday driver and I just want have fun with it on the road as much as I do when I play out in the fields maybe twice a year.

For springs I would run ls2 springs they cost around $100 bucks there good for up to .550 lift I know a lot of guys install them into there trubo camaros and they are running 10-9seconds in 1/4 mile.

Z28 springs used to be on ebay all the time pretty cheap...or just check forums like this.

I got my cam from Summit,,,,,believe it was the cheapest.

For a DD it could be.....may /may not need a higher stall. You may want to ask around to see if anyone has run it in a 350 (don't compare with a 383). You can't go wrong with the 409-8. I kinda wish I tried the 411 but would have been PO'd if I wasn't happy and had to swap again.

I'd ask around before going to the 411-8...just my opinion. Pm some experts like YenkoSt.....he's very knowledgeable about what makes a good DD. He should be able to help both of you.

[TheDuke90]

Alright man thats great so what do u mean by run out of breath around 5000rpm-5200rpm? with your cam in your truck

[93ChevyTBI]

Cams run out of breath depending on their rating which is based on their duration. Running out of breath means you've exceeded max power and it's starting to decline. I think Vortecs are rated around 5500 rpm whereas my cam is rated to 5k. So, theoretically, the heads can handle more cam...I just don't need it especially at the cost of low end torque.

[speedracer326]

Nope, stock WOT shift point is 5k. You can go 5200 if you want to hit the next gear at a higher RPM, but that's it.

[93ChevyTBI]

ok....I thought they'd go further...my mistake

[Pauly]

I rev my stock L31 to 5900rpm, but the stock rev limit is 5600rpm. The stock L31intake limits the power at rpm no matter what cam you use.

peace

[TheDuke90]

have you ever had your truck dyno with your cam? 93chevytbi

[93ChevyTBI]

have you ever had your truck dyno with your cam? 93chevytbi

nope...thought about doing it but I didn't think my curiosity was worth spitting out like $100-$125/hr. DD says 320 hp 440 ft/lbs....torque is what I chose it for b/c it's not like I'm gonna be racing the big heavy thing. The only time I put the pedal down is passsing and it brings a smile to my face every time......so much that I tend to hold it down longer than needed while my wife is screaming to slow down :cool:

I have never tried it but I'd be wiling to bet I can smoke a 5.3...especially a shorter race. I rode in one and they are good on top but damn it takes a while to get going....mine doesn't.

[TheDuke90]

well my truck as sit blows 5.3 out of the water pull truck link everytime with my old 2wd 96 i would pull 2 truck links on a 5.3 so you should blow one out then. thats not bad on hp, im starting think about running the same cam as yours. you have a youtube or some vido of your truck? What type of mpg you get?

[93ChevyTBI]

sorry..no vid.

get 11 city and 13 highway mpg

[TheDuke90]

Well if I went with other cam wut would i be geting in mpg?

[93ChevyTBI]

no idea...maybe same, maybe slightly less

[TheDuke90]

Tough choice lol I'm thinking get the more agressive cam because with my 4.56 gears set longtube-headers 2.5in running true dule with x-pipe and my 85mm tb plus when i get all this install im going go take the truck in to get tuned and dyno with right tuner I should be good thats what im thinking because i got a frind that has an 04 k1500 with 6.0 shot headers 4.56 gears and he was getting 12 mpg then when he got his truck tune he was getting 18-20 mpg

[93ChevyTBI]

don't think I would believe anyone who says they are getting 18-20 mpg out of a 6.0....tuned or not. Ask/check around here....it ain't happening.

[TheDuke90]

Well thanks man Youve been a huge help now you got me down between two cams now im going post new tread about the two cams see what everyone say and think which one be better for my truck.

[1995mudslut]

If I was you i would be looking for an lt4 performace cam.Not the lt4 hot cam as that one has too much lift for the stock heads.You can however run the lt4 hot cam if you get some beehive springs which will give you up to 5.25 lift on stock heads.

The lt4 performance cam will give you a nice little boost of power for cheap.If I am no mistaken you can still run the stop springs with it aswell.Check some corvette forums for people selling used lt4 cams.

[93ChevyTBI]

Lt4 cams run at least 20 less ft/lbs if I remember correctly. I had that on DD simulation too. I had probably 10-12 simluations. Perhaps better mpg though b/c of the lsa

[TheDuke90]

not bad Idea there pertty close to the 8-411-8 comp cam but so far chppest i found is 200 bucks =/ for used cam

[TheDuke90]

I just got done talking to comp cam and they told me for running a non carb vortec that i should not go no lower then a 112 lobseperation this is the cam he sent me told me replace springs and also got get head work cut the vavle. tell me what you all think he said my truck will though codes and not run happy with a 111 lob to me thats bull **** cause stock lob on a vortec cam is 111 also told me i need do head work if anything over .470 lift well if that true im leaning tordes the 08-409-8 cam

http://www.summitracing.com/parts/CCA-08-501-8/

[93ChevyTBI]

I also think it's BS what he said about the LSA b/c stock is 111. Several years ago that 501-8 was pretty popular and there were several for sale on here. I really don't know how that would run but it is a 212/218 cam so it would have less low end torque than the 409-8...should be close to the 411-8.

Shouldn't be any codes when the tune is done.

[TheDuke90]

Thats what I was thinking also looking online and reading more in detail between the two cams I'm pulling more for the 409-8 cam cause what i read is that the 411-8 really shine when its midrange power and i want something get me off the go and the 409-8 by sounds of it dont need do any work to my heads and also will give me more of the tq then what the 411-8 will plus the 409-8 is shifting at stock shift point.

[93ChevyTBI]

here's a little info I dug up lt4 vs 409-8

http://67-72chevytrucks.com/vboard/showthread.php?t=372884&page=2

guy had both cams in same vehicle

[TheDuke90]

ya well forget that Ill pay the exstra 200 and be happy with what I buy and spend to get my truck tune lol ya im going go with the 409-8 did u replace springs on ur truck or just install the cam?

[93ChevyTBI]

just the cam

[TheDuke90]

nice alright man well im going with the same cam as you Ive made my mind lol thanks
