I'm stumped. No TSM I have has the exhaust valve timing. Intake yes, exhaust no. Odd. It's not exactly popular information so it doesn't appear on the world wide series of intertubes. That's for the OHV, I assume it's different than the flathead, but who knows. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
