Re: What should I do
A C6 is the simplest and most direct way to go if you want an automatic. As to a rear, you probably have something suitable in the truck right now to get started. I personally don't like anything more than a 3.70 gear on the street. You will also need some sort of a posi unit.
390 crate engines are not that easy to find and tend to be expensive. Consider a 408 Windsor engine. If you go with the 408, use a C4 instead of the C6.
1966 Falcon, 347 stroker and C-4
