It's your truck, but if it were mine I'd be looking for a 261 chev or a 270 or 305 jimmy engine. All are inline sixes, and would make good power plants for a cool period hot rod. Pump a 261 chevy up around 200-225 horses and you have something that will impress the hell out of all the young guys and their rice burners, and wow everybody at shows and rallies. Putting a modern V8 in that truck would be like putting fake boobs on Britney Spears.
