To make the divots for the new style main bearings, the crankshaft will have to be removed- - - -no room to do the grinding for the tabs otherwise. It's about a 1 hour task to strip down a block, and doing anything else during a rebuild is a fool's mission- - - -too many places for bearing-destroying junk to hide. Bring it on- - - -I've seen what the ODSS crew can do when an engine buildup is in the works- - - -they make worker bees in a big hive look lazy by comparison!
