Good To Know

Q: Is jetting and tuning needed after installing this carburetor? A: Yes, a double pumper this size usually needs idle mixture, accelerator pump and jet changes to suit your engine combination. Final calibration depends on displacement, camshaft and altitude.

Q: Will this 850CFM carburetor bolt to a standard square bore intake? A: It uses the common square bore flange pattern found on most aftermarket 4 barrel intakes. Confirm your manifold flange style and available hood clearance before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
