I became a Pontiac guy because my parents bought a 1965 GTO in 1983 that had a 350 Chevy in it. I drove it with the 350 for five years, joined the Army, and the car sat in limbo and restoration for a couple decades. Now it has an IA2 in it and will probably never have another Chevy engine in it.
But my 72 Chevy longbed K10 might get a Pontiac engine one day
