I would guess the weight is about 4500 lb. and the drag coefficient is about 0.45. Good tires are important to reduce rolling resistance. Maybe you can reduce wind resistance with some modifications in the grill area.

A modern overdrive transmission will help a lot for highway fuel economy if you use a V8 engine. A good camshaft will also help. A single pattern camshaft (same duration intake and exhaust) like the Isky 256 Supercam should work well. I don't think they have one for a Cadillac but they do have them for other GM V8 and V6 engines.
