Q & A

What's in the Box

Offenhauser Triple 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 "big base" carburetors (2-15/16" bolt centers) typical of 1954-1962 Chevys.

  • Fits 235-261 Chevy 6-cylinders
  • 1950-59 engines w/ PowerGlide
  • 1953-59 engines w/ Manual Transmission

 

Included linkage kit is "non-progressive," meaning all three carbs operate at the same time.

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 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.

NOTE: To use on 1954-1962 inline six head, you will need to supply a 1937-1953 style gasket, a pair of washers and stud seals typical of '37-'53, and a pair of acorn nuts to fit the long studs that come with the cover. This cover is a direct replacement for the 1937-1953 Chevy.

216, 235, 261 Chevy 6 Cylinder Headers, Stainless Steel
                        

The 216/235/261 Chevy Six was built from 1937-1962 in cars and trucks. Our tube steel headers allow you to run a split exhaust. If you wish to run exhaust heat to your intake manifold, these headers include weld-on bungs which can be used to pipe heat to your intake manifold. Includes manifold gaskets, collector gaskets, flanges for the dump tubes, and all hardware.

  • 2" outlets
  • 1-3/4" and 2" primary tubes
  • 7/16" thick head flanges

NOTE:   Headers are purposely relieved for additional clearance.

Note: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.
