Very cool. Is the 453 a three cylinder? In high school (way back in the 70's) I was driving with my dad up a long steep grade in the mountains of Arizona when we were passed by a 67 Chevy 3/4 ton with an over the bumper camper and pulling a large boat. We were going about 60 MPH and so we sped up and found that the truck was going 75 MPH up the hill. We had trouble keeping up him in our unloaded Chevy truck - also a 67 that had a 283. We flagged the driver down to see what he had and he had a two stroke 3 cylinder diesel that he said came out of a crane. Ever since then I thought it would be cool to put a big diesel in a small truck.
