Adapting stock air cleaner to modern Edelbrock carburetor

[patrickaturner]

I recently purchased a 1964 Riviera that has been updated with a modern Edelbrock carburetor. The previous owner decided to also go with an Edelbrock air cleaner which I am not fond of. Fortunately, I have the stock air cleaner and hope to install it. Has anyone found a solid way adapt the old air cleaner with its 4.125" opening to fit a modern carburetor with a 5.125" opening without adding too much height?

I'd try the usual adapter from NAPA and see if you have clearance to the Hood. They're cheap.

 

The other way is to swap the top from an original AFB with that of the Edelbrock clone carb. The choke is different but will work.

Most of the usual parts store adaptors are for the opposite condition, mounting an aftermarket filter to an older carb. On a similar Mopar situation I used an adapter kit for two barrel to four barrel that actually worked, I'll try to find the number.

IF  you could find one, the 66 Riviera Gran Sport used a 63/64 style pancake air cleaner. If you're familiar with the 66 Riviera, you'll know that those engines came with a Rochester Quadrajet carburetor. The Qjet and the aftermarket AFB's, both Carter and Edelbrock, all have the larger 5.125" air horn. That's what someone has done here.

 

 

Or find an old Qjet air cleaner, cut out the hole, and weld it into your stock air cleaner.

Not sure what my air cleaner is off of, but it fits the Edelbrock perfectly. I t was on it when I bought the car. I put the decal on it.

Tough enough to find a '66 Nailhead Q-Jet intake manifold! The image is the 1st I've seen for a '66 Riviera GS, must be ultra rare like the 2X4.

The guy that does slip under furnace replacements could probably knock one out in 10 minutes.

 

Along that line of thought, we taught a novice some basic tin knocking skills. He transferred them to cardboard and started repopping Barbie boxes.

 

Shouldn't be hard to roll one out.

Hi Patrick,

I have a '63 but that had a 4GC, and now has an Edelbrock 1406. But if both the carb and air cleaner base have the same geometry as a  '64 I can send you some pix and specs on what I have as an adapter. Please let me know.

I spotted this on ebay which appears to be designed for this scenario, but have not purchased it myself.  Also unclear if the added 1" height would be a problem or not.  Pricey too.
