Long time friend and customer, Charlie Bowers wanted to freshen up his 1966 Pontiac 389 engine after logging over 180,000 miles!  Charlie purchased his black on black ’66 GTO brand new, and he felt it was time to have us go through the engine.  Charlie was looking for a basic “stocker rebuild” with some slight upgrades so that he could run on the pump gas of today and still produce the power that he remembered the car making.   We used the original 1966 block that came out of the car and after chatting with Charlie about his goals for this engine we started on this very tame and reliable pump gas build.

The engine uses the following components:

  • Stock 1966 2 bolt block with armasteel crankshaft
  • Stock 093 heads, screw in studs installed, new stainless valves, springs, guide liners, spring, retainers, keepers
