AFR225's What kind of results should i expect with a set of AFR225's on top of my 383 ls1? They are milled to 59cc and my compression will be about 12to1. I do not have cam specs but it will be aggressive (as big as i can go that Pat G will suggest). I just read that a guy with PRC 2.5 heads got some good numbers on a mustang dyno. I have an A4 with 3600 stall and 10 bolt at the moment.

I made 463hp 414tq with afr 205 heads on a 346ci ls1,m6 car. Also,i was on a mustang dyno that i lost 25hp on when i went to it from a dynojet. You with the RIGHT set up should get 450hp to 460-ish-hp. Match your intake,cam and heads and you will have a fast car.

I made 470 hp/ 440 TQ , with old LPE 243's heads, FAST 90 unported, 23x/24x cam. Tune was suspect though as far as timing.
You should be somewhere in the 450-480 range easy.

You should send the heads to Tony and let him work his magic on them. Take a look at my sig. I made 484/412 threw cats with a 346 and afr 205's and supporting bolt on's.
