new cam and heads for 2012

Im planning on going with a custom grind 232/240 578/574 110lsa over my current cam which is 230/236 576/571 113lsa. This new cam matched with my le2's and le ported intake should see a decent gain im hoping. Any ideas on how much power ill pick up? I run low 11's consistently and break high 10's occasionally with my current cam and stock milled heads with a 150 shot.I wont be installing the new heads or cam until im done with my forged 358 this winter. Also open too different suggestions for a cam as well. I have a hughes 3000 stall right now but im gonna go with s looser 3600 because my car wil l roll through the brakes at 2000 with my current converter.

Re: new cam and heads for 2012

This is for a forged 358 not what im running now. Since you asked I have the stock crank micro polished and turned, stock reconditioned resized "forged" rods, clevite main and rod bearings, hasting rings, speed pro 30 over hypers. I've sprayed it 30+ times with 100-150 shot but I wanna go big so im going with either a howards or scat forged rotating assembly, with j.e forged pistons or diamond forged pistons. May go with an ultra lite set of rods and ultra lite scat crank

I may go with le biggest cam with a 108lsa with the new forged motor. Low end loss is not an issue with me because I plan on running a loose converter 3600 stall and with 4.10's the car rarely sees under 2k

Re: new cam and heads for 2012

Lol with my stock heads,intake,52mm tb, 576/571 230/236 113lsa, I only made 320 rwhp on a mustang dyno. That's with full bolt ons and PCMforless tune. The dyno 's elevation is 2000 ft higher then where my car is tuned for. The worst part is I went back with a 150 shot and only made 370rwhp but made over 500 ft lb ds. Something seemted fishy too me. I don't think the kid new how to run a eddy current honestly because i've ran a 10.8 and consistent low 11's and a full weight camaro just won't run 10's with only 370rwhp. Track times is what counts in my book
