Time for an update. The 906 cubic inch V-12 just wasn't big enough. I bought a 1,790 cubic inch motor to shove in it (same kind as Blastolene Special). I'm going to try it with the big 4 speed first.

I also have decided on wheels and tires. Classic medium hole Alcoas. 22.5 x 7.5 with 255/70/22.5 tires on the front (36" tall) amd 24.5 x 8.25 (duals) with 285/75/24.5 tires (41.5" tall).
