thoughts on main bearing Babbitt ??

[Richard Knight]

This is still a good discussion. The key here is understanding and believing that interrupting the oil film is a bad idea. This is really undisputable but still not understood by many. Some folks seem to think model A bearings are special or unique, they are not, they are "plain" bearings also known as friction bearings. Babbitted early V8s did away with the elliptical grooves going to transverse and annular type of groove. My own B with the brumfield 5.9 head, downdraft, and other mods has no grooves in the main caps, annular grooves in the rods and No shims is probably still running down in texas as I sold that car in 2010. My major point is directed to the folks who say that won't work. Well if that were true then why are there millions if not billions of plane bearings in virtually all automotive engines that seem to work just fine.
