Here is what I have so far.

383 stroker lt1 -forged Rods, Hyper. Pistons, 9000series Crank
Comp Cam -.556/.576-top end to match (springs retainers)
Lt4 Manifold
Lt4 KM
Cai
1le 90*
Mac mid lengths
Flow master cat back
and few other random things
With all this I dynoed at 330rwhp with a dead map sensor and timing retard like 10* because of false knock due to sensor. My fuel curve went from 11.4 to 17.5. I am hoping to break 400rwhp on stock heads with 58mmTB, Cutout, Map sensor and some serious tunning with Lt1 edit. Oh ya and I am getting my tranny built for 700hp with a 3600 stall TQ next week.

Now to what heads I should run-
I was thinking AFR 220cc heads Comp pkg. but I also heard of some 227cc heads( don't know anything about them.) with hydra rev kit. The fuel system to match.

I also want to know if I am going to be able to spray a 100shot once I put heads on or is that too much for my bottomend.
