I measured the line bore at 70 degree room temp then stuck the block in a parts washer at 170 degrees and then measured the main clearance again and it opened up .002. So if I had .0025 clearance cold I would now be at .0045 with the block at operating temp.





Dont forget your crank at 170 degrees would be larger also.
