I found an article about a flat head rebuild.
Go to www.systemv.us and then go to the engine section. he talks about the flat tappet engines which apparently need zinc in the oil... which is not there these days. An interesting read.
yes Lynn. In nascar racing a few years ago the small block chevy suddenly started to wear cam lobes and flat bottom lifters .They queried the oil companys , the only thing different was the removal of zinc in the oil .It didn't seem to worry the roller lifter engines .Bryan
