Aluminum oil pan

I am currently in the middle of a 396 stroker build up, and I am looking for an off the shelf aluminum oil pan for a 340. I am having a really hard time finding one, so I'm hoping that someone might know of a company that makes them.

Call Kevko 800-770-3557, its a small mom and pop shop that answers the phone and has a great product.
part number is M301a for the stock sump location $735.00
