The Pontiac 326 was produced in '67 and '68. It was the grocery-getter motor in Poncho full-size, and the base V8 in '67-68 Firebird. Usually mated to a 2-speed SuperTurbine 300. This engine has 3.718" bore and a 3.75" stroke. The main journal diameter was 3.00" All '59-'79 pontiac motors used a water pump mounted into the timing cover, a valley pan, non-adjustable valvetrain and a reverse-rotation CCW distributor. I doubt that parts from a Pontiac engine would fit any other engine family.
If you find out otherwise, please let me know.
Good luck
