How does the coil still work? will i have to keep the harness in the truck for it?

 

well, just outa curiosity, why do you want to switch to carb? efi is a much better setup. i think you could just replace the coil with a carb coil, if theres any difference.

 

I put a 95 mustang engine in it.. and the compute wont accept it. I would have to change to mass air and its like $700 bucks.. I already had the carb stuff for a mustang project

 

also for the throttle cable what year truck do I need to tell them? and the kick down cable to i guess.. AOD.. Also how would i hook the temp gauge up.. thanks

 

well, for those, i dont think it would matter, but im not sure.

 

The temp gauge and oil pressure switch are just single wires, so it would only be a matter of finding where it went between the engine harness and the cab and lengthening the wire. Same with the tach as far as I know.

 

This is my first post here and I'm going to resurrect this thread because I'm doing the same thing as 92flareside. I have a '94 Mustang motor that I want to put into my '92 F-150 4WD with E4OD transmission and run it with a carb. This is not my daily driver and over the next several years it will be an on-going project. Yes, EFI is better and at some point in the future I will do the mass air conversion. In the meantime I need to get this truck running before ordinance enforcement notices.

It looks like I'm going to have to use the truck oil pan, timing cover and accessories. Does anyone know if the '92 302 engine is a 50 oz imbalance or will I need a new flexplate? I will also need to get a fuel pressure regulator with a return outlet to reduce the fuel pressure and get a distributor with either vacuum or mechanical advance.

Have I overlooked something? Thanks for any help you can give.

 

If you are going to mass air later, why go to all the trouble of converting to carb in the first place? I'm not trying to be rude, but I just think it would be easier to save the trouble of converting to carb if a year from now go through the trouble to un-do it. How are you planning on controlling the transmission with a carburetor (the E4OD is controlled by the engine computer). Although, are you sure it isn't an AOD? If it is, that's one less thing to worry about since it is not computer controlled.

 

If he's anything like me, I can understand. I really dislike EFI.

 

No, you're not being rude. I don't know the answer to the question so I'm asking to benefit from your experiences. In short my reasons for converting to a carb come down to time and economics. I've got most of the parts to do a carb conversion laying around and I can find the others quickly and cheaply. It also has to do with my formative experience in auto mechanics. Fuel injection back then was mechanical, expensive and impractical. I didn't own a fuel injected vehicle until 1987. I never tried hot-rodding a fuel injected vehicle until I got my '94 'Stang several years ago. I've got over $1,250 into the induction system alone (manifold, injectors, TB, Powerpipe, MAF) at this point and I still need to upgrade my fuel rails/regulator (another $400) and get a chip or a good tune on the car.

If someone has a VEX1 or WAY1 computer and wiring harness laying around that they would sell me cheap, I would go that way.

As far as the transmission it has the 20 bolt pan so it would be an E4OD. Please correct me if I'm wrong, my understanding is that if I left the stock computer in, the trans would still function. I read an article about a mass air conversion at www.fordmuscle.com/archives/2005/10/MassAirConversion/index.php that said (just above the reference to this forum) some E4OD owners run a Mustang computer to handle the engine functions and keep the speed density computer for transmission function. I would assume that the VSS and maybe the MAP sensors give the computer the speed and load info?

I found out that the 302 engine is a 28 oz imbalance so I need to use my HO motor balancer.

 

I'm not really sure exactly what sensors are needed to control the transmission in stand alone form. It can be done, but I really don't know what all is involved with that. What is wrong with the truck electronics now? I think the carb conversion is do-able if that's what you decide to do.

 

The bank to bank electronics don't like the SEFI injection engines.
