Hi, I gotta question for you since you're doing this and probably done what I'm going to do. I have a 440 crank cut to b mains, I have a very nice 400 block, I'm going to mock up the b-rods & pistons to get a visual on just how far the deck clearances will be. The question is, I'm sure of bearings needing champers but have you just cut them with a carbide or something to just make some mock up bearings ?
