Rated 4 out of 5 by from Simple setup Happy overall, but the hardware needs to be updated. Mounting bolts were too short. All in all cheap and easy way to mount a 1406 Edelbrock.

Rated 4 out of 5 by from Would work perfectly in a different application. I purchased an Edelbrock carburetor from Jegs and they recommended that I use this adapter for the Quadra-jet carburetor manifold I had on the car. However, the Edelbrock manual specifically stated not to use this adapter for this application (open square hole). So I had to get another adapter from the local parts store to replace this one. It wasn't worth the postage to send this back, so I still have it sitting here, maybe ready for another project....
