263 Buick Street Build

I have done up a couple of DynoSym5 files for a stock 263 Buick, and one on a 263 I am putting together.
If you use DynoSym5, you can take these files and drop them in your "Engine File" directory for future use.

If you improve these please post the improvements back here!

Are the head flow numbers measured from an actual 263 head or are they the generic files built into DynoSim5? How extensive is this build going to be? Are you planning to have the head ported? Custom pistons for improved compression ratio? Maybe some custom built headers?
