I'll be :flame: by some for going from EFI to carbbed, but that's my decision. Anyways what will I have to change as far as distribuator, linkages ect
Search, I have posted in a thread with the same question. A few answers, fuel, ignition, throttle cable and some wiring.

p.s. Carb is the way to go.
the absolute worst fuel injection is better than the best tuned carb. why in the world would you want to go back to that all a carb will do for you is make it so you have to tune more and you will never get the tunning as good as a fuel injection system will. but to each their own. i just dont understand going to duch a poor design as a carb.
Carb's are easy to tune. Go to your local race track and see how many are using carb's. Carb is lighter and cheaper to do.

Carbs are easly to tune for a given scenario, but they do not offer the best combination of drivability and power over multiple variables. Anything I have that's carbed WILL be EFI in some form or another.
But hey, some folks thinks computers is hard and no where near as clever as they are.
The only positive I'll give you is that they are cheaper, but with the new batch of standalone systems, tuning is just as easy with an EFI system and more consistant.
Anyway, I know there been a couple threads on this subject, so go through the old searchorino...
go to carbdford.com, they have lots o info.
Easy change over throttle linkage can be bought at your local parts store, You will need and intake, i would suggest the edelbrock airgap or performer RPM, you can use your existing ingnition mod and dist but i would change over to the MSD6AL and MSD dist.
I'm sorry to say that I don't think CFI (the worst form of EFI, at least among our cars) is better than anything. CFI is a turd, it's junk. It should be replaced, always.
Carb's have been around since the early 1900's to the late 80's on cars. So all this time they were junk? They couldn't combine driveability and power? Let me ask you this, of all the small engines out there, guess what the choice is? Carb. On your motorcycle, quad, snomobile and dirtbike. One of the main reasons why fuel injection is here in todays cars is emissions. Dollar for dollar in a naturally aspirated car, carb will make more HP. Heck if they didnt, why do they make a carb manifold for the DOHC Cobra motor? How about the carb'd LS1 motor? Dirt track guys used carb, NASCAR uses carb even the fastest speedboats are carb'd. Now I'am not going to sit here and tell you FI doesnt can't make HP cause it isn't true. In naturally aspirated form, carb makes more power. Now I'am talking about in a street strip fashion. I'm not talking about everyday vehicles but in a performance form and affordability.

For old hot-rod geezers who are lazy and afriad of computers.
OOOO, I just had to do it.
I think carbs are still cheaper in some aspects (all things considered). And easier in some ways. I could have had HO wiring, computer, and intake manifold for my 302 - but I ditched that shiznit real fast for a Edlebrock carb'd intake.
I never said that carbs were junk...but compared to EFI, carbs can't match the combination refinement and power.
Of course when carbs were de facto there had to be "driveability"....but again that's relative. Also, making them more "driveable" always resulted in a compromise of some sort on the performance end of thing. The main reason you still see them used on off-road recreational vehicles is the fact that they are cheaper. For maximum performance you still have to fuss with jetting and other aspects.
All my "performance" cars will be EFI....you can keep your carbs. I messed with them, tuned them and have moved on. I want real-time datalogging and the ability to "tune" on the fly and have an engine management system smart enough to cope with environmental changes.
How is that setup you're working on anyway?
I'll let you know when it's powered up in the car. Harness is made, power wires run....but no battery yet.....moving it inside behind the pass seat.
I have no worries about it working as intended though...just need to get it done.
Carbs have their good side. Switching from CFI to carb on a 1984 5.0 Cougar/T-Bird is about the best thing one can do to gain performance. SEFI is wonderful for daily driving, for highway cruising, and even for the strip when tuned properly. Any time you want fuel economy, SEFI is king. But for cruising only or at frequent trips to the track, there's nothing wrong with a carb. It is something different too. I've been hearing from a lot of owners lately that switched to carb and they love it. If it's something you want to do, I say go for it. You will have no regrets then.
yeah, I like EFI,all but my ol' Poncho Parisienne were multi port EFI. sensors can cost alot. I'm going with carb now because of my budget...getting a Edelbrock 600 cfm e-choke with only 10 min on it for $100. I'm also planning in maybe a year or so to put on a roots-style blower *single carb, will fit under hood* Now after awhile I MIGHT go to an aftermarket tunable EFI setup. So could change things as I go.
