To improve gas mileage in a 1978 350 V8 El Camino, consider performing regular maintenance such as tuning the engine, replacing spark plugs, and ensuring the air filter is clean. Upgrading to a more efficient carburetor or installing a fuel injection system can also enhance fuel efficiency. Additionally, maintaining proper tire pressure and reducing excess weight in the vehicle can contribute to better gas mileage. Finally, adopting a smoother driving style by avoiding rapid acceleration and heavy braking will help maximize fuel economy.

My 1972 SS with a 350 gets about 16/17 mpg
Yes
A 350 CID w/2bbl carb will get you the best mileage and power.
You probably need to be a bit more specific. I've got a 1972 El Camino with a 350 engine in it. I get about 17 mpg now that I just put new spark plugs and wires in it.
Probably. 9 years ago, I put a new 350 crate engine into my 1979 El Camino, which was originally equipped with a 305. Bolted in and re-used all ancillary components, including carb and intake. Still running.
K&N air filter is the best way
yes, all you need to do is change the motor mounts and put in a bigger radiator.
350 c.i.d.
The only 350 available in a 1984 El Camino was the diesel. If your V8 isn't a diesel, it's a 305.
probably a turbo 350.
