Also Chevrolet did use a bolt in motor mount that used a setup like this. Olds did too. And from the looks of the pipes, it could have been either one. I would figure that it had a small block chevy in it.

I am thinking I can run a similar engine mount similar to what I have in my C50.

It is a horseshoe shaped motor mount that attaches to the front of the engine and sits on a cross member with rubber bushings. I then can build a cross member for the tail of the transmission.

That may work, but I'm thinkin that the holes are too far apart and too far back. If your C50 has the front trans crossmember, measure from the bolt hole to the bolt hole in the u bracket on it and measure from the trans crossmember to the center of the three sidemount bolt holes on the side of the block. That will tell you if the van had a front mount or side mount. I think you may have side mounts. Here is a link to the side mounts that I'm thinking of. http://www.napaonline.com/Catalog/Ca...108_0434791927

You're making some major progress.

Looking at the motor mount crossmember and bellhousing crossmember, I would say that a small block was in there utilizing the motor mounts linked to above, with the '73+ exhaust manifolds.

Personally I would change the differential to either a 14 bolt or Dana 70 with 4.10 gears. I would still go with a 4L80E. However if you are planning on some tall tires a 4.56 gear may be better.
