Rebuilding a 460, EFI or normally carb?

[btsave]

Hi, had a recent engine fire in my '63 Galaxie, with a transplanted 460, 4 speed manual, power brakes, mild cam, Holley 830 4 BBL with mechanical advance, MSD 6L.

here's the link:

My question is... now that I need to replace the card, wiring, hoses, brake booster, belts, MSD, front harness... what can I do to both increase performance and, of primary importance, increase gas mileage? I currently get an average of just 6mpg which limits my enjoyment of the car.

I am considering an EFI... but don't know what choices I should consider nor whether a normally aspirated carb would be better... most of my experience has been on mouse motors, so this BBF is still relatively alien to me...

Any suggestions would be helpful at this point.

Thanks!
