    Rated 5 out of 5 by from Upgrade Good carburetor but did not fit out of the box. I had to add a 2 inch spacer to get clearance from the intake. The fuel line interfered with the distributor

    Rated 3 out of 5 by from Extra parts needed The carb looks good. Holley needs to be clearer on where things hook up PVC port. Step 7 says hook up PVC hose - to where ? If you are using this carb on a Holley cast iron intake ( 1966 ) you need this gasket and stainless plate for the exhaust crossover . Also could have the rubber grommet for the throttle linkage. I had to order from another company

    I have a 56 thunderbird with a v8 312 will this work for it

    Asked by: Scott25
    The Holley 510-0-80508S carb is universal fit for square bore intakes. It is possible you may need an adapter to bolt onto the 312.

    I got a chevy small block 350 and was wondering if this would work

    Asked by: Zebadiah34
    This will work in a higher rpm performance application. Most small block Chevy engines work well with a 600 cfm carburetor.

    Asked by: jim miller
    You will want to lean the carburetor by reducing the jets sizes, reduce the size by 2 numbers until you find what your combination likes best.
