Thanks guys! Hey Skip, long time no talk! Work on any tigers lately, lol!
Here is an article on cylinder head flow. In engineering it is called "Mach". Or the speed of sound calculations.
Mach discussion
The things we like in stock and super stock is that are getting good power from the OEM stuff with rules. Of course NHRA gives all the advantages to the SBC guys, so we have to spend more and work harder just to stay even. The Pontiac guys are always a step ahead because they have to be.
It is a nice challenge for guys that like to work with the original stuff. We are approaching 600HP with a 400 6X motor with the stock compression ratio bored .060 and 3.785 stroke.
That is what makes it fun for us. Approaching 600HP with a 6X motor with stock runner volumes is killer. We have a lot of fun.
