you have more head flow then me, more and more duration then me - so if your mot making 600+ you're doing something wrong.

What are you doing for the crankcase? evac? vac pump? breathers? I saw nice gains going up that ladder.


I've got about the same compression ( 10.50 :1) and the most power was made with a 1000HP holley at 65-6600 rpm.

regardless of cam, intake or head I made 560 - 566 tq but I am running a longer stroke - @ 4.125
I also probably have a lighter bobweight, but I am really not sure if that would show up - @ 1749 grams
