I've been around Hot Rods and racing my entire life. My grandfather, Ollie Morris, was head engineer for Offenhauser from 1954 to 1986. Almost every intake manifold that Offy has was designed by him. Because of his work, I grew up surrounded by high performance cars, hot rods, race cars, etc. I bleed motor oil.. If I can't answer your question, I'm sure my Grandfather can. I loook forward to chatting and throwing my 2 cent in on the board.
