Cam question...again!

[Hivelocit]

So I have been deciding on a cam to throw into my 5.3l block, and along the way contacted Comp Cams listing the mods going into my 88 GMC Sierra. They forwarded me a cam profile stating that it would yield good gains... thought I would share it with you guys and see what anyone thinks, pros-cons? Is this a streetable cam or is it too mild? Looking to make a fun truck out of it, not necessarily for the strip, but laying some nice burn marks on the ground would be nice!

List and things to come are 3in exhaust, ls1 or ls6 intake, no head work till much later down the road.. planning on keeping it N/A... gearing and stall I am a little unsure about at this point in time but someone's opinion would be helpful since this is my first conversion! Thanks Gang!

That is certainly a streetable cam and not too mild. In fact, IMO you are probably gonna wanna go bigger. Thats not much lift and it has a 5000rpm maximum range??! LS motors love rpm and if I was going to bother putting a cam in I would definitely get one that has a range more like 1200-6500rpm. It all depends on how modified you want to go but IMO If you are gonna get one this small I wouldnt even bother. Youd be better off with an LS6 cam.

i would do like a 212/218 the cam u listed above is not uch bigger than stock

Flattopwill, how well do you like the TR220 was it just what you were looking for or do you wish you went bigger? Also what springs/pushrods did you go with for that cam? Looking around on the internet it seems like quite the popular set-up!

[blackjack325]

i did the same thing. comp suggested
part# 54-455-11
215/223 dur 604/610 lift
i posted a thread in the mechanical section:
http://www.ls1truck.com/forums/mecha...-comp-cam.html

maybe the guys reading threads here will give another opinion

Thanks Blackjack for that thread, surprised I didn't run into it sooner... Good info there! Guess I will do a little more research on those cams although my truck is only a standard cab, and hauling is not so important to me prolly the tr220 will be the weapon of choice, unless someone else has a different opinion I'm all ears for the time being! ALSO: whats the main difference between the 112 and 114 LSA I know the lopiness is different, and although I like lope I want something just a little quieter, would there be any real difference between the two driveability wise?

[blackjack325]

no prob ^

i know the 112 will be choppier idle. the 114 should be pretty smooth. As far as street driveability, i did advise comp that my truck was daily driven and thats the cam they suggested. I dont go to the track much, just a few times a year. I will be going with the LSR cam myself

I do like the cam very much! I have the 112 LSA and it gives it a mean hot rod sound that gets a lot of attention. There are minor power delivery differences between 112 and 114 LSA but mostly it comes down to the sound and what you want the truck to do. If you just want it to be quiet, smooth, with some more power then go with the 114. If you want that hot rod sound then go with 112. Personally, I love how my whole truck shakes just sitting still and how everyone wants to race lol. Everyone thinks I get bad mileage too which isnt true!
I have stock push rods with LS6 valve springs. I dont recommend this pushrod/spring combo with this cam just because it is stretching the limits of the valvetrain. I did it because I was on a serious budget and was willing to take the risk. If you keep an eye on the forum classifieds you can find some Comp 918 springs that will hold .600 lift for around $100 and some Comp 7.4 hardened push rods for ~$50.

Hot Rodder say "cam is like penus. Whenever you go to use it you always wish it were bigger. "

[Hivelocit]

Thanks Flattop I will keep my eye out for those springs/pushrods, and check around the internet some! Ya the 114 LSA I believe I'll like since it will give it that "sleeper" appeal to it, although what muffler are you running with your set-up I have the 70 series flowmaster on mine perhaps that would quiet it down?

LOL... ya but I guess you have to stop somewhere or else the girls wont want to sit in it!
