Improve performance and remain Emission Compliant! Replace your worn out Rochester Quadrajet with a new 1975-1978 650CFM Holley Spreadbore Performance Carburetor. This Holley carburetor is set up with an electric choke and vacuum secondaries and the spreadbore design is a direct fit on stock 1975-1978 Corvette intake manifolds designed for the Rochester Quadrajet carburetor.
Note: May be adapted to earlier applications. Provisions for electric choke (12v) will be required for pre-1975 Corvettes originally equipped with divorced choke.
NOTE: Always purge fuel line by cranking engine before connecting to new carburetor or after any carburetor service. Most carburetor service failures are due to immediate rust/dirt contamination caused by the high volume of fuel transfer during initial float bowl fill.
