Help me identify.

Hey everyone. I recently bought a truckload of parts off a older gentleman that had a transmission and general repair shop. Saw a ad in the paper, called him up and before too long I had a truckload of parts. One of those deals, buy everything to get what you want. Got 2 700r4's in the deal, along with some other interesting items. I got this bellhousing. The guy said it was for a straight six. He had a customer order a new trans. This bellhousing came on the transmission. He used the owners bellhousing. Put this one on the shelf. I'm needing to know what it goes on. Any help would be appreciated!
