Default Re: Holley Carburetor Conversion

Brian,

I too have made the swap to the 2-barrel set up. My carb is a Holley 4412 model. I found a dual intake and installed that using the Mr. Gasket adaptor as stated above. I used the Mr. Gasket air filter designed to fit the Holley $20.00, I cabinet blasted and painted it under hood black.

The other issues I ran into was the accelerator bell crank throttle hookup. The carb is wider, and the alignment is thrown off. So, I simply made a new linkage. (See pics).

I recently changed transmission and went with a wire cable throttle set up.

I also wanted the look of an oil bath type air cleaner, so i used the base from the new Mr. Gasket breather as the foundation (fits the top of the Holley) and I set an oil bath cleaner on top (after I removed all the steel wool and cut the guts out) I used a correct sized diameter dry air filter for the inside.)
