I just built a iron block 408 11.5-1 comp. with -10cc diamond pistons,eagle crank,eagle h-beam rods with a (texas giant cam) 248/254 622/611 114,PRC stage 3 ls6 heads and I have a direct port nitrous setup how much do you guys suggest I run I was thinking 300rwhp shot or maybe 200rwhp if thats to much I have a progressive controller

 

Pretty close to my set-up. If ya have the L19 head studs then a 300 plus would be doable with a spot on tune. I have them and have allready been hitting it with 260rwhp and plan on going to 350rwhp. (l19s have 40% more clamping force to help keep the heads down).

I have ARP headstuds and cometic gaskets

 

Standard ARP head studs, or the upgrade ARP L19s?
