Q & A

What's in the Box

Offenhauser Dual Carburetor Chevy 194, 230, 250 and 292 intake allow you to run a Big 6 without the hassles and cost of the GMC. Manifold provides a nostalgic appearance while equalizing fuel distribution to all cylinders, improving both performance and economy. With this lightweight cast aluminum manifold, your inline six will be more responsive across the RPM range.

Accepts two OEM (Rochester B or BC) 1-barrel carbs like the original on your 1963-1975 straight 6. Manifold comes with a non-progressive linkage kit.

Notes

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 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.

This polished Offenhauser finned aluminum valve cover will shine up your 194-230-250-292 Chevy 6-cylinder from 1962-1975.

  1. This cover has one hole for a filler/breather. We suggest Twist-In Breather 550-2061.
