flowed an intake port today.
cfm @28 4'' bore w/clay radius
.100-67
.200-124
.300-175.5
.400-222
.450-225
.500-217-216\/
Definite shape issue
The peak about hits 227-230cfm around the .470 lift...but it's too shaky/turbulent to be able to hold on. the ports are polished to hell.
gonna work the turn some and then just rough the rest of it a hair and retest.
