I have heard of .700" lift out of a 300 six at ford six performance index owned by a guy with the screen name "frenchtown flyer".

I question
1. spance between piston and top of combustion hamber

2 how much the head will allow

I have heard of a 300 with headers, offy intake, holley 450 cfm 4 barrel, 240 head, electronic ignition making 300 hp at 5500 rpm and over 400 lbs of torque at 2500 rpm if I remember correct.

I wonder what a 360 can do with 9.5:1 comp, 4 barrel, 230 D @ .50 cam , headers.
