I have seen several Later Model GMC vehicles with Pontiac Engines installed by their owners. In all cases the owners were very happy with the engine swaps.
Typically they were the 455 engines with the T-400 Trans swaps and in a few cases (with guys that built Transmissions) they installed a Switch Pitch converter along with the proper trans.

In 1971, a Pontiac Guy named Ralph Piper had a early GMC truck with a 1965 Tri-power engine and good tires that would run 11.70s at US-131 Dragway in Martin Michigan.
