It's a datsun engine, probably out of a 1979 or 1980 B210, with an automatic transmission. The auto trans was the key part here.

I probably won't deal with putting it in the car until this fall though. Too many other things on my plate this summer plus I'll need to spend some time scrounging for some parts on ebay and at swap meets before it could go in the car.
Getting it was exciting though. The truck died on me right on Novelty Hill Road!!! Couldn't be at a worst place. So I end up blocking the uphill lane on a curve waiting for AAA to come tow me home. Now I have a truck that doesn't run that I'll have to deal with.
