Nothing cheap.

Figure your current mpg. If you improved it 20%, where would you be? And how long would it take to recover the money for EFI?
A good running carb, decent compression, headers, will get you the best mpg from an FE at the least cost.

Yeah the cheapest one I found was $3800. I could probly do t.b.i but wont be any improvement over stock. I think your right, ill just figure out the proper size carb for a 390, im thinkin 750+ cfm, it already had a mild cam and headers now.

500 or 600 would be better for mpg....

if I go to small you actually use more fuel, theres a fine line to walk on lol. I think im going to get a 650 holley and have it tuned, theres also bodies you can buy with interchangeable venturies but thats a different story lol.

I too have been through this before and totally agree with 85 E 150, a 500 to 600 CFM would be a much better choice, you certainly will not be getting better fuel mileage with the 750. Us the CFM calculator link.

Hmm have you tried looking at one of these? I like the projection 1 personally.

Several places sell them and Gen 1 will connect to everything including the intake and throttle linkages. The price tag is still $2000 but it is a sleeper system.

Or you can go with this and not thinking of mounting a seperate brainbox.

You can also use the holley 4x4 carbs that have offroad provisions incorpated into them so you can run them in funky positions. I know they have a bowl vent tube that runs between the bowls and vent whistles so you can go over 37* and not dump fuel.
