I agree with Dwight......I have used spacers that we made from std. bearings in a 400 block to install a 350 crank for a 377's. We line bored the bearings to size. I went thru the trouble of drilling thru the bearing spacer into the main saddle and tapping the hole for a machine screw. I used countersunk headed screws and ground them down to be sure they sat below the surface. Never had a problem using those for myself or my buddy and he really rpm'ed his stuff!! His motor generally saw 8200 on every run.....
