S-10 chassis
Personally, I'm not a fan of the S-10 chassis - the track is quite narrow, as are the framerails. I'd rather use a car chassis (g-body GM, for instance) or in your case, the Volaré/Chrysler 5th Ave/Diplomat/ETC K-frame swap is popular - complete self-contained front suspension and engine mount provisions for a Chrysler V8. If you wanted to put a Chrysler V8 in an S-10 chassis, you would have to use the less-common rear sump truck pan and then you may have exhaust issues. Plus, the frame rails end up under the seat, which makes it hard to channel the cab over the frame. Lastly, the leaf spring rear suspension isn't easy to Z, but a car 4-link already is.
Either way, good luck. [S
