Quick update on the dart: The 440 block is getting line honed. As it turns out, the main studs that were in the indy aluminum block 572 will in fact work just fine in a stock block with stock caps. Might as well use them since I have them. Thus the line honing. Also, the crank that was in the 572 has an 8 bolt flange, and my stock 440 crank has a 6 bolt flange. There is a spacer that gets sandwiched between the flexplate and crank as a part of the adapter setup to mate the powerglide to the mopar engine. I had a machine shop make me one of those but with the correct 6 bolt pattern.
