I aggree Jim... I just thought I would toss these numbers and parts
out there for those who like going the Cubic Inch route...
I'd rather have some AFR's or Merlin 16 degree BBC heads than cubes.

It's interesting to note what appears to be a very small amount of surface area on that car, John. I'm sure the people who did it must know what they are doing but I'm wondering about how it was selected.
I have heard about people using the 383 and having a 3" high air cleaner elements with a drop base. It seemed like they were very concened about having lots of filter surface so as not to choke the engine.
I would guess that the type of filter media would come into play, but is there some sort a formula for area of air filter needed for 'cubic cinches' or 'air volume' ?
