1967 Chevy Camaro SS Heater Box Firewall Cover, Big Block
- Good Quality Reproduction
- Great For A Daily Driver
- A Must-Have For Big Block Conversions
- Includes Big Block Tube Plate And Gasket
The Big Block heater box cover is different from the small block cover. The big block heater box allows the heater core tubes to come out through the middle of the cover because the big block is much wider than the small block. Trying to use the small block cover with a big block makes connecting the heater hoses almost impossible.
