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.
