That's a skillful build. As a Jeep fan, I like these old Jeep pickups. A V8 is a tight fit because they were designed for four-cylinder engines. The tailgate plaques are a cool idea. Some guy near me has a teal Willys Jeep Pickup that kind of looks like this one. I can tell it's not stock because he takes it on the highway.
It looks GREAT. But no way in hell would I have put a computer engine in it. It deserves a REAL engine. If it were mine (and I wish it were) that engine would be the first thing to go. I would drop it off at the local landfill, and put a carbureted 383 in it.
