This is actually one of my uncles good buddies build. He is a welder and had a lot of help from a few other guys building this monster from the ground up. Its got twins on it, should be featured in a few diesel mags soon. I havent met the guy yet but I saw one of his other rat rods, I think it has a 454ci with a 14-71 roots on it. One of the coolest rides I have ever seen do a burn out. My dad rode in this one 2 days ago while he was up in billings, ride of his life.

btw, the green crank on the side is actually hooked to an ignition switch, it starts the truck when it makes a full crank.
The bumper on the rear is made from pistons from a cat. Full rollcage in it with aluminum buckets.
