I like the idea of a D-100. With a 318, it will likely have better fuel mileage than a slant6. Plus, you upgrade wheels, and things easily as you decide.
Thats what I was thinkin', I am not looking for another project, but something that I could do upgrades too a little at a time. Its going to be used probably more for the diy renos and putting some car parts in. In all reality a slant sick a body would be the daily driver and the truck used when need be.
