Speedmaster vs Edelbrock air gap intakes

The Edelbrock is a better cast unit with bigger runners and ports. The more powerful the build the more you’ll feel the difference. How well they compare on low power builds is a good question. If the build is a real low power deal, the smaller ports may prove to be advantageous.

I have zero complaints about mine on top of a ‘00 - 5.9 with a Edelbrock. carb, Hooker 1-3/4 - 2-1/2 exhaust, 727/3.55’s on 245/60/15’s, chrome boxes ignition/JY distributor. The ride pulls nicely from idle to about 5K.
