The "Road Trip" version Aftermarket and factory components 5.7L crate engine Celebrate the Jeep legacy Retro is the rage these days and to help celebrate the Jeep legacy, Chrysler recently built this "Road Trip" version of a 1965 Wagoneer and added a 5.7L Hemi V8 and 4-speed automatic transmission. They used a pair of Dana 44 axles and also stretched the wheelbase some five inches plus moved the wheel flares up six inches to clear the 33-inch diameter mud tires and 17-inch steel wheels. Tie the Gear down! Don't forget the COOLER Just in case. How about this road side rest. It's all about taking an old Jeep and adding perfection to it, thanks to the availability of numerous aftermarket and factory components, namely that crate engine.
