Dodge Mini Van Replacement.

Ok I know this sounds like a strainge topic for a Hot Rod club, but here goes. I just purchased a 2001 Dodge Grand Caravan, and my wife wont let me make it a "Hemi-Van"..so I had an idea.
I was thinking old...like in the late teens to thirties dodge wagon or some sort of delivery van, on the ground and Turbo Cummins powered. This way I would have a lot of torque for the heavier older cars and still fit well under the hood of an old straight eight bodie of some kind..
Has anyone heard of simmilar projects or have any ideas of a doner vehichle, as I am not a Dodge guy I have a hard time choosing a vehichle.
Thanks for any input, Chase.

ive got a neighbor down the street, he built a towing truck for his huge tri axle fifth wheel, almost semi length trailer. he got an old delivery truck, put a cummins turbo deseil semi drive line in it with a single cab sleeper. painted it fire engine red. it looks like a mini semi and will pull anything attached to it. but it was a huge undertaking to get it done.
