just a quick comment about the gas mileage in the Cadillac:
i have a 1970 472 Cadillac in my 76 C10. Its a 2wd shortbed, has a TH400, 26.6" tall rear tire, 2.73 rearend. The engine has been rebuilt to stock specs, and has dual 2.5" exhaust. in my light shortbed i get 10mpg even with a light foot. :-( no fun to pay for fuel, but its a fun truck and has TONS of power.
also sucks paying for rear new tires all the time lol
Yeah, no overdrive and a 26.6" tire. All that torque has nothing to do--what RPM's do you run around 60 mph? I would think that going to a 31" tire would net you much better acceleration (you could use a lot more pedal off the line without spinning) and way better fuel mileage . . . .
