Call Aviad in California (
http://www.aviaid.com/pdfs/cat05.pdf) they have the small block pans in stock on the shelf. You do not need a dry sump system but a good
oil pan is worth its' weight in gold. I think the cost is about $500. You won't be sorry even if you only ocassionally track your car.
Tell Richard, Reg, any of the other Backdraft team I said hello.
