I am looking for 500 Crank Hp or around 435 RWHP. Will I get there on a LS1 (M6) with the following: U/D pully, cold air intake, LT headers, 226/232 .609/.604 113LSA +2 cam, 5.3 stage 2.5 heads and fast intake. I want to keep a somewhat stock idle.

 

It will be close

 

thanx, anyone else

 

Port that FAST 90 and if you have a good flowing exhaust it's possible. Not too sure about the bumpstick though. What cam is that? Custom?

 

Look up Tony Mamo's build with their AFR 205 heads. Key are heads and properly ported FAST 90 or 92.

 

I put 435rwhp 390rwtq with the same heads and a 234/234 cam. Fast 90/90 not ported and all supporting mods

 

Heads and cam selection are key. Give us a call, we can get you squared up with a setup that will do what you are looking for easily.

Thanks,
