The Stovebolt Site Forums The Shop Area Paint and Body Shop engine paint color?

GMC did, in fact, use Pontiac engines from 55-59. GMC was preparing to introduce the V-6 motor that they used from 60-68. They were expecting to hit a home run with this motor, and the pontiac motors were used as a stopgap until they were introduced. Unfortunately the V-6 never really caught on with the general public.
