List,

I just finished tearing down the 72 engine and I cant believe what little if 
any wear there is on the cylinders, pistons and all journals.

I cannot detect any wear at all. Very little carbon on the top of the pistons. 
Rings are still very sharp. Cylinder walls are nice and smooth with no ridge 
at the top.

I wont know for sure until the machine shop mikes it out but this engine seems 
like the OD reading of 43 K must be about right.

Although there is sludge on the bottom of the oil pan and the block had about 
1/8 to 1/4 inch of crud, the internals are very clean.

Thrust washers are still in place and show very little wear.

The only reason I questioned the mileage was due to the amount of rust on the 
rear b-post, fenders, and lower rear apron.

The car is a southern tier NY car though.

This engine is not 1 143K engine.

Bob
