Rat rods are not my discipline, but I have to admire this man's ingenuity. Watch this video all the way thru. You may not be into big diesel engines, but this man sets a huge V-12 Detroit with 71 cubic inches per cylinder on top of a Turbo 400 transmission that he has to shift manually, since there is no vacuum in a Detroit Diesel. This has to be one of the more unique rat rods I have ever seen. The guy put a huge amount of work into it, but he also put massive amounts of himself into the project, and I have a lot of respect for that.
Someone might donate one of those belt-driven vacuum pumps like GM used on their cars powered by an Olds diesel. I'm surprised he didn't think of that...
