Now this all has got me curious about exactly just what engine I stuffed into my 240, I only know it was supposedly from a newer car, that its a 5 cyl 617.?, the vac pump looks a little different in that it only had one port going to the booster instead of 2 ports (original had a second to air cleaner lid) and that the box of accy's and parts that came with the motor had a cylindrical shaped ac pump instead of the black round Delco unit in mine. Never got to see what car it came out of. Guess I oughta go check the stamping again..

Camshaft! Dangit I just got back from the wreckers this afternoon too...
I know I need one, can visibly see a higher ridge along the non wearing edge of a lobe.
