Hi- one of the problems with babbit and old cars is, when the crankshaft is ground to smooth, the babbit gets thicker to make up the difference. Babbit, while a great bearing surface, is a very poor heat conductor. Thus, thicker babbit means more heat retained, shorter bearing life, premature failure.

There’s a place in California (and I’m sure others could do it) that builds up the side of rods, and fits a modern bearing insert into the rod. The purists may be aghast, but it makes for a more reliable engine when rebuilding.

I like keeping things original, but some things can be re-engineered with not affecting the original “feel”” of the car.”
