Tim Borrall manifold test
#1 your head port 4 or 5 slightly cleaned up with no intake on it
#2 your head w/ OOTB 440 RPM intake
#3 your head w/ ported 440 RPM intake. This intake made 640 LB-FT and 627 HP on a 496 stroker with a bigger solid street roller but with heads that only flowed 292 cfm @ .500” and 309 cfm @ .600”. Again, your head is in column #1
#4 your head w/ ported 6-pack intake
#5 your head w/ported Victor 440 intake, slight mismatch as the intake opening was bigger than your head port opening (wrong way mismatch).
Lift...........#1............#2..........#3...........#4...........#5
.100..........77...........77...........77..........77...........77
.200........157..........157........155.........156.........153
.300........228..........217........224.........222.........230
.400........283..........246........264.........262.........279
.500........328..........270........286 ........291.........312
.600........341..........276........297.........295.........326
.700........337..........284........309.........301.........332
So we’ll test combinations #3, #4 and #5 on your engine.
