When considering insert conversions don't forget the 1935 and up rods used flanged insert rod bearings, and the 34 and back were also babbitted on the side faces of the big end to obtain the correct side-play clearance between the crank cheeks. Brazing "nubs" on the sides of the rods and filing or machining to get the correct side-play has been done and apparently successfully, but has never sounded like a great idea to me.

CCCA had some good technical articles on this type of conversion some years back. Send me a PM with your email and Ill send you a copy.
