Manifold Test - Ford Racing Boss 302 crate engine

Death of a Small-Block

By , Photography by , Grant Peterson

Edelbrock Super Victor
The Super Victor was another nice surprise. It made almost the same average horsepower as the 2x4 manifold, the most average horsepower of the five manifolds tested, and stayed near the average torque numbers made by the best dual-plane. What has to be looked at are the peaks. The Performer RPM made peak torque 1,000 rpm lower in the powerband than the Super Victor and more horsepower in the usable 3,000–5,500 rpm range. Those lower rpm numbers equal driveability in a street car and is the fundamental difference between the two designs.

I'd lik to see the same test using the wilson spacer on the rpm airgap intake. I use a funnel web(equal to the super vic) on a 302/5.0 motor in my 90 coupe with tfs 3 cam, ported world sr heads that has very good street manners and drive anywhere with 4.30 gears.
