I used this plus a Mr Gasket 1937MRG adapter to install on the 283 in my 1957 Chevy. It's a straight bolt on with the adapter and ran perfectly right out of the box. I didn't even need to adjust the idle speed. Starts / idles / accelerates waaaaaaaay better than the original Rochester carb. ***********************************

I would definitely buy again.

Absolutely thrilled with the carburetor. I simply put it on, hooked everything up, cranked for a second to get fuel, and it busted right off. I made one simple idle screw adjustment to my liking. Runs awesome.
