Dang! That's a lot of copper showing on the bearings! The 70 413 I recently rebuilt (quickly shade tree job) didn't have any copper showing! Lots of grooves in the throw in your picture. Tell the machinist you want the crankshaft "indexed ground"! This insures all rod journals are 90 degrees from each other! Mopar cranks I've ground have been damn close, but ask for it and pay the difference. That's one of the ways to make real power!
