A Guide to 1967, 1968 & 1969 Chevy Camaro/Pontiac Firebird F-Body Heater Core Sizes

About halfway through the first-gen (1967, 1968, 1969) Chevrolet Camaro and Pontiac Firebird production run, General Motors switched the small-block V8 equipped cars from a 2.5-inch thick heater core to a thinner, 2-inch heater core. And this little change has caused a lot of confusion for F-body owners restoring their 1967, 1968, and 1969 Chevy Camaros and Pontiac Firebirds. To help ensure you order the right size reproduction heater core for your first-gen GM F-body restoration, we created a helpful guide that will show you how to check your heater core size.

When you’ve figured out which size you need, you’ll find the right heater core for your Firebird or Camaro restoration at Summit Racing.
