A little advice please

I like the concept, I had a Ford with a Mopar engine for a while and it was awesome to piss of the Ford guys. I like diesel trucks, but personally not a fan in cars. No good reason why. Did you consider an efi 5.0 and overdrive? A fox body or truck donor would be dirt cheap. If you want to go mopar an efi 5.2 or 5.9 swap would be cheap and easy, and I have a 68 fury driver setup that gets 20mpg with this combo. I say build whatever you want, that car is probably worth max 15k with a 30k resto.
