Here are some quotes from "The Model A Engine" by William and Paul Mcree:

"No one should use lead based babbitt to rebabbitt a Model A engine."

"Insist on the use of a XXXX nickel base babbitt for your Model A engine."

"XXXX nickel base babbitt is suitable for both mains and rods. It is a very tough tin-base bearing alloy. The dense fine-grained structure, high Brinell hardness and special combination of ingredients in xxxx nickel base babbitt give it the properties necessary to resist all but the most severe punishment. Since the Model A has no oil filter and Model As are driven harder now than was ever intended, this babbitt is a must."

If some other babbitt is used, it should meet these specifications:
Brinell Hardness ........24
Compression Strength....13,625 psi at 10% deformation
Pouring temperature.....800 F to 950 F
Liquid at.............669 F"

The foregoing quotations appear on pages 19 and 20.
