ok kool, my friend asked what my motor should be making with the old cam and new cam, do you guys have any idea?

the old cam was the 306 .575 lift with 260@50 duration
new cam is 282 .540 lift with 244@50
its a 360 kb107s 10.8 compression
stage 2 ported 360x heads
crosswind intake with holley 750 dp

That might make 450 at the crank. Depends on how well the heads work.
I did a 340 with that kind of cam, compression was only 10:1, victor, 750 and mild port eddy heads and made 455HP.
You could also go with full ported eddy heads and roller cam but it gets expensive...
