switch to carb
How hard is it to switch a late 80s early 90s f-150 from efi to carb? I've been looking for a 80-86 f-150 but I can't find one, atleast not one thats in good shape. So I would like info on switching from efi to carb

On the pre '90 trucks it's relatively easy, strip the motor and bolt on a carb and intake, and then delete the frame mounted high presure fuel pump and just use the low pressure in-tank pumps to feed the carb. You'll also want to make sure you get either a manual, C6 or AOD tranny.. not one of the computer controlled trannys.

I'm looking for a a truck with a manual tranny, so that won't be a problem. My only concern is any thing that goes through the computer. So what you are saying is that I can just take out the computer and not have any problems. What I'm wondering is, is there any sensors that are needed with a carb setup that run through the computer?

BTW, If you do find a running EFI truck you won't gain anything by switching it to carb. And if this vehicle has to have emissions tests it won't pass with the carb on it.

No emissions tests here in Minnesota. I want a carb so its easier to work on and I like carbs better, plus there is a wider range of parts available and they are cheap.
For sensors, I'm talking about the sensors for the check engine light, oil light, etc.

let me butt in here with some advice, from reading your other posts your wanting to run 2-2bbl carbs on your 302 and your looking for economy.....for all the research and thinking your doing you could get all schooled up on FI, find a 90's truck with a 351w which will probably get you better mileage than a carbed 302 and more get up and go

Easier to work on with a carb?
My computers tell what's wrong. Even when my wife can't put the gas cap on right. Can't get any better than this.
Your efforts to go with a carb would be better spent understanding the FI system. It's really not that hard, and a good scanner helps.

I have looked at efi, but from what I've seen, parts for the efi system are more expensive, and for what I want to do to the engine, a stock efi system won't be able to keep up, I'll look some more but I don't think I'm going to find much. Besides I just like carbs better, I'm old school, but born into new school stuff.

I won't even go into the advantages of FI, it's been said over and over again not only on this, but most other forums. Many people are even converting their '60, '70's muscle-cars to FI. As for a stock EFI set-up not keeping up...who says you need to use one off a 302??

Yea I was born in 89, whats yer point about most trucks having efi after 87? I know that, I don't care about the so called advantages of efi. I just looked up prices for a bew throttle body and an intake, and it was around $800 combined, I can buy an intake, carb, and headers for that price.

You can safely bolt on headers, upgrade the cam and port the stock heads, no changes to the EFI electronics or intake manifold necessary, and you will see lots more power. How far can you go? About 300hp is the answer, after that is when EFI starts to require upgraded parts on these trucks.
