And a .040 over size pistion is 3.9150 Dia. ? My largest cyl-Bore Dia. measured from the top edge down the cyl. .250" is 3.9096. Most other cyl's are around 3.9088 So would I use a .040 over size pistion? Or can I get by with a .030 over size? The block has not gone to Machine shop yet for re-Bore & Hone job. All so my CRANK mic's out on the Mains at 2.2985. And on the crank pin it mic's out at 1.9994 So would I use .001 over size bearings? Or STANDARD? | | |
