You may want to check with IHRA on your cam specs. You may be pleasantly surprised by the duration numbers. I would also get the valve spring pressure from them as this was my limiting factor when I ran Pure Stock. When you get these figures, it will be easier to choose a convertor and gearing.
Good Luck,
Joe
