6.0 heads 8#s of boost race gas, What cam stock bottom
6.0 heads 8#s of boost race gas, What cam stock bottom Okay i am thinking of changing my heads to 6.0 heads and running 8#s of boost with 110 gas. What would be a good cam for this setup it is a stock ls1 5.7? Thanks guys for any help Also what should my timing be set at for this right now i am at 29* timing 5.3 heads milled .020 and a f1 cam .591 -.569 lift on a 112lsa running 5#s of boost with 110 gas. What should i do thanks guys
a small cam like a Z06 or LPE GT2-3 cam would work very nicely,if your planning on getting a forged shortblock down the road,call up Comp, Futral,HPE,or Forced Inductions about a custom grind cam for your goals.go to http://www.forcedinductions.com/help.htm and scroll down to the cam section for help

You need a little bigger lobe separation to maximize your boost potential. i would go with a 115 lobe cam. Your lift looks fine. A reverse split cam allow your engine to maintain more boost. The intake duration should be larger than the exhaust. MTI makes a G1 cam for blower/turbo application. My two cents. 
If you have a good tune you won't need 110 octane. I was running 11 psi with a 67 on my stock motor, 91 octane, no alky, just intercooled boost. I can't do that in the 100+ summer temps though. Below 85 degrees it was a non issue.
For a cam choice, i'd run a z06 cam if u can get one really cheap.

When you say stock bottom... that include Pistons? My TA is at Fastech now to get tuned and I elected to stay below 8#'s.... due to the pistons. How long did that work for ya?

I'll post up if I ever break the motor. It's got 74k miles on her now, been boosted for 13k miles now I think.
PS, my low boost setting is 7 psi.
To do what i'm doing you need to have a REALLY good tune, thats hard to get unless your tuner knows turbo cars well.
Shawn from Fastech is Tunning my car, and from what I hear he is real good. I am using 918 springs... so you have a 76 on there now? I think I am going to have my T60 ported for a 67 wheel.... Stay around 7-8 PSI. I am hoping for a solid 525RWHP
