Build sheet had .020 for the mains and rod bearings. / I did check the main bearings - they say .030 - so I guess that is the truth. Will look at rod bearing sizes.
*Car had very low compression - so I wouldn't think about detonation too much. (4x heads off of a 74 and 30+cc dishes on the forgings.) *Car did have a HR cam - WITH a bronze gear (first thing I replaced). At least I THINK it was a bronze gear. I KNOW it's not composite. *The cross-hatch in the cylinders still looks very good. (looks like a two-year old build in a car that was taken car of) I'll pull the crank and have a good machine shop check the main and rod journal sizes and (I guess) consider a polish if they're okay. Also - I appreciate the advice about the oil pump. Interesting - I don't really do this stuff.... .I guess I do now. So much for just changing the rear main seal..I APPRECIATE the help - keep it coming. Last edited by GTOLou; 02-12-2008 at 08:40 AM. |

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.
