Are you sure they are Pontiac? Pistons are pop-ups, very high compression for racing or could be used with large chamber heads to boost up compression. That does not seem to be a TRW number, most are an "Lxxxxx" type number. JE is a piston manufacturer, so it might be their piston, but I could not find anything under that number or ID the piston top.

Cam looks to be a roller cam. I can't read the stamped number under the ink writing. May be a Crane cam?

Connecting rods are not cast. Those look to be forged H-beam.
