If you want to eliminate fuel waste you need to go to a modern EFI engine. Mileage on these things was unheard of just a few years ago. But you must bring all the systems with them to do this which can be complcated and expensive. But modern performance in power, mileage and low emissions is nothing short of stunning. This upgrade would also need to include a matching modern transmission as the combination of lower low gears at one end and high overdrive ratio's at the other a powerful partners to these new engines.

Everybody uses this technology so pick the maker you like, go to the wrecking yeard and buy the whole vehicle to salvage everything from the gas tank to the radiator. Older Throttle Body Injection will double the mileage the same engine got with a carb example would be the Chevy 350 truck went from 9-10 miles to the gallon with a carb to 18-20 with TBI. The next generation L31 Vortec with seqential injection gets about 22-26. The new LS series engines see about 26-30 mpg with a huge power increase over anything that came before along with a major reduction in emissions without a bunch of gadgets hung on the motor. The other brands show same similar results.

Take a look at modern machines and your old Rambler will look like something from the Fred Flintstone era.
