Choose around your actual engine

The application is the 1968-1982 C3 with a small-block Chevrolet engine. On a chassis originally supplied with another engine, the installed-small-block requirement still applies.

A size choice for your build

The 1-7/8-inch primary size is the difference from the separate 1-3/4-inch version. Match it to your engine and intended use, then have your installer check the car’s engine position and chassis clearance.

Tuning for your exhaust upgrade

We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.

Matching products

For the same 1968-1982 C3 small-block installation, compare the 1-3/4-inch C3 headers if the smaller primary size better suits your engine specification.
