    You better first make sure the crank does not have GM selective fit bearings, if it does you MUST regrind the crank as you cannot buy selective fit bearings anywhere ever.

    select fit bearings? Well i measred (mic.ed) the jurnals an they were a frogs hair from 2.09 inches So looks like I have been running standerd bearings when i should have been running .010 overs /forums/images/graemlins/yikes.gif The funny thing is that i have drivin it like this for probly about 1000 miles and my only sign was low oil pressure and a rattle above 4000 RPM. But let me tell you that i did not assemble the lower end I had my mechanic buddy do it and he obviously did not check to see what the old bearings had stamped on the back of them before he went and ordred a set of standerds. Any woh got the new ones in now and they feel much better. No more grabbing the rod and being able to jiggle it around on the crank. Didnt get a chance to fire it up yet though cause my bank is closed i got no more money. So we'll see tomorow.
