Interesting contribution. Thanks! I have done a little searching on the list but never seem to have time these days to read through a couple dozen posts.

Keep it coming and don't worry about hi-jacks or changing the discussion to cams, lifters or anything else that helps make HP. It's all good.

BTW: I know we could use a higher lift cam or longer duration cams in our engines, but does anyone know how much air will flow through a stock "S" as it was manufactured? That would be interesting to get a real base line on the engine as a unit, then work your way up from there.
