You'll have to use an aftermarket crossmember and mounts to install the V-8. Also, you'll need a bellhousing from a V-8 era truck, you'll have to modify the steering column and box someway to make room for the wider engine, convert to 12 volts, etc. Your rear end should last up to the point that you start driving the truck,LOL. Don't know how well the headers will fit, but I know rear dumping manifold will. Welcome to the Stovebolt,
