What I was Thinking aswell. Gonna be hitting it with a 200 shot aswell. Hopefully the cam likes it as much as I think it will

Your cam is essentially the same as mine if mine were hydraulic other than mine is 113 lsa.

Your heads likely flow a little less than mine.

I'm not super familar with the LS2 intake results once they are ported.

My car made 438rwhp but only ~380tq. I think yours will make more tq but the gain of the cubes might be offset by the heads and intake. If I'm underestimating them, then you could do better.

My heads are 799s milled .015" with a valve job and full hand port by a SAM student. They seem to work pretty well but not as well as the best CNC 243s or aftermarket. On proper size bore plate they should flow 295-300cfm intake.

My intake is a Fast 90mm that I ported the wedge out of and tried to smooth rough spots.


EDIT: I also always forget I'm putting power through a heavy *** 3.5" steel driveshaft and a 12bolt too. So you very well could do better.
