there is a lot of info on this topic using the search function but to convert there is a lot to do if you want it to look right.....the benifit to carb will be quick fast tunability by yourself if you know carbs..and you won't have the dreaded idle surge accompanied with an efi car........

yeah you gotta love the idle surge though... with a gear drive it sounds like a injected blower motor. mine surges really bad with my cam, then once the car warms up its fine...

Going from EFI to carb gets problematic on cars where the computer manages more than just the engine.

has anyone ever done this, because i was going to do it too. Is there a big difference in gas millage? if anyone knows let me know

I converted my 85 cfi fuel injected mustang to carb........If you tune the carb right there won't be a real noticable reduction in fuel milage..but all that is dependant on your carb tuning capabilities

i have a 1991 stang that i put a worked 351w carbed. and i love it sounds go with the carb. Took out my engine harness moves any wires i need in to the inner fender and i am running a autometer gauge cluster that i had to wire up, and i had to run a 3 foot wire to the fuel pump relay under the seat cause the efi harness has the wiring for the fuel pump relay. wasn't that bad just takes some time.

yeah thats what i thought but one of my budies was like the fuel wont atomize as well as it does with a efi. so he thinks ill just get dumpy millage.

even you got dumpy milage, to me it would be worth it. no sensors or bull****, injectors, nothing! you buy a nice single plane intake and like a road or street demon youd be good. Im planning on doing a sheet metal intake and running an Avanti carb, if any of you are familiar with those, very nic carb. youll pick up a few horse with a good fuel system, ect. electric watr pumps are nice, single wire alternators, and your gauges. im already runnin everything mechanical except speedo, im planning on tearing th stock gauges out make a carbon fiber panel or whatever, and shove a 5" speedo and tach be done with it. i got some pretty good info doing this from a fellow forum member and its sounds scary but also sounds fun because it would be a project of its own in a project!! as tradecki stated it takes time!
