318 head porting for the average joe
Ok ..so i ported a lil more on them today. I did a lil short turn work up to the straight wall ...at 1st it seemed to pick up a few cfm on the lower/mid lift, but it led to turbulence and the flow dropping off at .550 with 192cfm...but nothing major at all, even rough cut still.
----CFM@LIFT----
.100--63.7
.200--127
.300--172
.400--185
.500--190
.550--192
.575--187
