Overall Assessment

Customers appreciated the quality of our carburetor adapter, noting its perfect fit, ease of installation, and ability to increase horsepower. They highlighted the material quality, stating it was well-made. It was noted to work for various vehicles, from a '65 Corvair Corsa to an '86 Oldsmobile Cutlass Supreme. Users could easily adapt different carburetors, such as Quick Fuel 650 cfm, Eldelbrock, Demon, and Holley with our adapter. Recommendation was high, with many expressing plans to buy again. However, some users suggested purchasing extra mounting hardware. But overall, the adapter was welcomed as a cost-effective solution for carburetor adaptation.

Great item for the price

I had an intake that was not a dual bolt pattern (Holley only). Wanted to bolt on a Q-Jet with the least expense possible, and this item fit the bill perfectly. There were two reasons that I did not give this item five stars: (1) You need to re-use your Q-Jet bolts with this, and I did not have those, so I had to buy. The kit comes with short studs; and (2) there were quite a few molding/flash lines on the adapter that I need to de-burr to eliminate stress points and sharp edges. Other than that, if you need a cheap way to convert from square to spreadbore, this is a good product to accomplish that.

Works ok

It fit the manifold and carb like it should however the gaskets are crappy because they didn't fit the side profile of the adapter and looked bad. I trimmed them with a razor blade to get them to fit decent, meaning the gasket was bigger than the adapter and I was able to trim some off the sides

Worked well. It would have been nice if bottom gasket was bigger and had both sets of holes in it so the studs were easier to utilize. Other than that real nice product for price point.
