Had machine work done on my block. when checking bearing clearances (King bearings) the math showed i would have over .004 clearance. http://www.turbobuick.com/forums/images/smilies/mad.gifTried federal mogul bearings too and they worked out to be the same. looked for bore size for bare bore can't find...they checked out 2.688..i assume that's too big. i want to know what they should be so i can straighten out the machinist who did them. also bought Cat rods and installed King bearings and they too were going to be too big when i did the math. (not my day for bearings i guess)http://www.turbobuick.com/forums/img/smilies/confused.gif No it's not my Mics either I used to be tool maker for a living they are good. What's the bore diameter size for the bare rods? crank measures 2.2495 (rod) and 2.4992 (crank) Good enough.
 
Mains: 2.688 - 2.4992 - 2*0.0934 = .002"

Rods: 2.3742 - 2.2495 - 2*0.0619 = .001"

Main shells ahould average around .0931"
Rods shells should average .0616"
U should be good.
