From reading all of the posts on this subject, it seems like it would be hard to decide exactly which way to go. If you did a lot of long distance touring, inserts? If you are like me and put less than 400-500 miles a year on a Model A, original babbitt? Babbitt (not Costello's friend) worked well all of these years. As someone else commented, the insert technology didn't exist during Model A's reign (at least in the low priced car field?) Our '36 Ford pickup has a 59AB flattie of course with inserts and pressurized, and I think nothing of running IT 55 MPH really buzzes along. With a higher rear-end it would be even better!!!
Hope Mark finds his late '31 block.

Jeff, they are inserts all right, but are babbitt lined inserts, and thick compaired to modern inserts. Some were also copper- lead, in which didn't work out to well the way I understand. As I here from other engine builders, some builders quit doing babbitt, and went to inserts, because they couldn't keep their babbitt jobs in. Anyway, the key to longevity with inserts in any motor is oil pressure, and Filtration. Here is what inserts look like when dirt goes through the bearings, less then a 100 miles, and as Kev says, it was towed home. Herm.
