Big Block Basic Application Info

Big Block Chevy Engines

These kits fit GM Mark IV, Gen V and Gen VI big block Chevy engines.

 


Harmonic Damper

Some factory Gen VI engines may have a different harmonic damper that must be changed. See picture below.

 

This is the factory Gen VI harmonic damper that must be changed. Notice there is no recess for the pulley boss to locate in.

   

 

This damper is representative of the vast majority of big block Chevy dampers found. Part #10216339 is available from GM. Always make sure your damper is the correct balance for your engine.
