Doing the frame off on the 70 .I have completed the frame and was going to freshen up the motor.I found three lobes round on the cam ..... #7 and #8 the piston skirts and cyl were scuffed enough to need a bore job i think .ill know more tomarrow .just wanted to know if anyone can tell me some things to look for?

Was the engine rebuilt at any time ? Through the years Ive seen some pretty tight pistons shoved in the cylinders - some machinists might check the top for fit, but they dont shove the piston down 3.5" or even 4.0 " to check the fit. As far as the lobes go - might be the original cam, just old/worn. Ive rebuilt/machined 4/6 and V8s through the years - and it always seems to me any cast iron American V8 (and old inliner sixes) will hide its illnesses very well; they will continue running for years, even in very poor health.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
