If you do not want a truck, how about a late 80's Blazer. Most parts are same as the trucks and the best parts supported older pickups around.
Or if off-road is not a requirement, an '81-89 Monte Carlo, preferably an SS model, nice older car, roomy, modern enough to have ac and cruise. Much more comfortable than muscle cars, came with a V8 and would be quite easy to swap a crate 350 or 383, or even an LS engine with some electronic work.
Yeah, I have thought about it a little.
