Don't gorget that you may have to clearance the crank to the block, and turn the 440 mains down to 383 size I believe. I may be mistaken!!

No mistake, that's correct. :cheers:

Either clearance the block a ton or turn down the counterweights and cut the mains from 440 size 2.75 to 400 size 2.625 IIRC
