Re: Need opinions on carb vs efi

The original and properly working induction system will work better and likely get better mileage than an aftermarket carb with an aluminum intake.

F.I. seems a large expense and more hassle than necessary for what now is a minor issue to solve.
A well sorted dual exhaust would probably gain more mileage than F.I. alone.

That's certainly been my experience, especially with aftermarket Holleys and Edelbrocks. It's always a battle between adjusting choke rich/lean setting and "fast idle" speed. And sometimes you simply have to go richer in winter and leaner in summer.

The last carbs I remember with chokes that worked well were late 60s and early 70s factory Q-jets with divorced chokes and choke pull-offs. Rarely needed to adjust anything on them to get consistent operation.

My buddy who's a Ford guy says the same is true of OEM Autolite carbs used in the 50s-70s.

Re: Need opinions on carb vs efi

Regarding EFI, a buddy of mine just ordered this setup:

I may get involved with the installation, and will let you know how it goes.
