What is the theory behind drilling the holes out on the direct clutch? It is just a cooling enhancement for street driven cars?

This is a race only car that is slowly inching it's way to I/SA as I save up the funds to replace the bracket engine with a legal stocker.
Thanks again.

Chad, I've seen that modification done, but not seen any real gain.

Honestly, the transmission for Stock will be very different. In fact, for your car, in I/SA, I'd be looking at a 200 Metric from McClay or Arnett. To convert your 350 to a class transmission, you'll need to replace both drums with aluminum drums, as well as having some other stuff lightened. The difference between what you're building now and what you'll need for Stock is about a tenth.
