My honest opinion of doing a 350 or 302 v8 swap.....cut all the crap out & run the vehicle like an old school muscle car. No power windows, locks, A/C, etc. Remember, it's a wheeling rig. All you need is the engine, tranny, steering, suspension, tires, and a seat for your ass. That's what I'm planning on doing when the time comes. Doors off & possibly even the tailgate. Install roll cage & drive it like you built it to be driven/off-roaded.
