Victor Jr EFI Intake

Port Velocity isn’t really the issue with EFI like it is with a Carb. Stock converter would have suited your old combo but I feel that it’s a fair way off with the new cam you’re running! Something with a stall in the 2800-3000 range would likely represent a good improvement.

Port velocity is port velocity regardless of how the fuel is introduced. Air has mass, faster moving mass has more inertia. Simple physics. Granted booster signal is taken out of the equation with EFI, but the basic principles of port dynamics are not.

The new cam is fairly mild, idles at 15" of vacuum, and that idle isn't very snotty at 700 rpm. Smooths out immediately. Hughes 2630 grind with their 1.5 roller tip rockers.

No on the 3000 stall in a 4x4.
