I know that every few minutes the forum erupts into a debate about motor oil, and maybe this was already covered, but in Hemmings Motor News there was a new oil announced called "Z-alt Musclecar oil" which supposedly has the right stuff for flat tappet camshafts. available in 10w30 and 20w50 it's 8 bucks per quart. www.z-alt.com Chris 3846
