Offenhauser 1034 Dual Carb intake manifolds provide a nostalgic appearance while equalizing fuel distribution to all cylinders, improving both performance and economy. With this lightweight cast aluminum manifold, your old “Stovebolt” will be more responsive across the RPM range. Use with two carburetors (2-5/8″ bolt centers) typical of 1937-52 Chevys.
Fits 216, 235, 261 Chevy 6-cylinders
1936-1952 engines w/ Manual Transmission
Included linkage kit is “non-progressive,” meaning both carbs operate at the same time.
Note: This intake manifold is designed to bolt up to the heat box on your original exhaust manifold. Exhaust heat must be routed to the bottom of the intake to help keep the fuel droplets suspended in the air/fuel mixture, providing better cold weather performance and overall driveability.
If using our split manifolds or exhaust headers, you must still supply heat to the bottom of intake using a heat box that you fabricate. This can be done by routing either exhaust heat or engine coolant to the bottom of the intake via copper or steel tubing.
Carburetor Port Diameter: 1-1/2″
