I thought the same thing about the holes in the bearings - and the gobs of sealer around the main.

"I believe my block was line honed or bored".
Bro - you take good pics which helps analysis. Not surprised of the piston wear versus the bore wear, looks like a little piston slap was going on, more common with forged pistons being a little "loose" if the block was honed/bored and not clearanced correctly (forged pistons expand more than stock cast). And the Valve stem carnage - that is a machining and set-up oversight With bad valve seals, maybe some oil/smoke blow-by was going on?. Not at all trying to throw darts here, just some input based on experience. You mention maybe going the Stroker route. What else is currently on/in the motor - ie carb, cam, rocker arm type and ratio, valve springs, etc? Was it all stock, or some different stuff when and if it was rebuilt? |

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.
