[QUOTE="DZL JIM, post: 1252156, member: 153"] I have 2 motors with spun bearings, the blocks and cranks are shot. The machine shop told me it's cheaper to get another motor by the time they weld to the block and crank and machine everything. The one motor was so wore out the flexplate wouldn't even engage the starter. When we pulled the trans, we could push the flexplate side to side about an inch. There's not an over-sized bearing in the world big enough to fix that. [/QUOTE]
