Edelbrock Air Gap 2x4

[jholmes217]

I know the FE Air Gap 2x4 doesn't alloy Holley carbs.  Has anyone tried to see if old Predator carbs would fit?

the people I know that have used a Predator at the drag strip always lost a couple tenth's over the Holley's , based on that I can't imagine the Predator would be any better than the AFB style carbs as a replacement

Can't answer the original question.  But if you decide to use the Edelbrocks do not use the 500cfm carbs.  Most simplistic booster design in carburetor history - so big and square that you cannot get them lean enough no matter what.   They roll rich at a pretty low RPM and just blubber along from that point on.  I know what they were trying to do, but its just the wrong approach to take.

Here's some good information that you may want to read if you get a chance.

The predators will physically fit either in line or side mount. Smaller footprint than the side hung Holley.  Two matched and tuned predators work really well together and fabricating a linkage is very easy for in line mounting. Id say use a 1" open spacer on a duel plain manifold with the predators though.  Predators seem to really respond to carb spacers on duel plains. I'm not a predator hater and own a few. They worked great for bracket racing and stay consistent.   JMO. We know what that's worth LoL .

While I've had good results with the Predator carbs in general, I'm thinking a pair of the 625 cfm Street Demons would be a good choice for the Edelbrock Air Gap 2X4.   At least they would bolt on whereas the Holleys do not.  The Street Demons seem to be a common choice for the new W series engines (409 based) that use dual quads and those make some good power numbers.  Ted Eaton.

Offenhauser makes a carb adapter to do that part number 5880 moves each carb a 1/2 inch.That may work for you. If you want to run holleys

I ran a pair on the dyno and thought I had two plug wires off....

Hmmmm.  I wonder if medium riser or low riser fuel logs and linkage would work then?
