Hey guys, Im sick of my SD and i acually had thoughts of switching to carburated. So what are the EXACT parts that i can get from a junk yard needed to convert over to MAF? Im also not spending up to 800 bucks or more on a Kit. If it comes down to that il switch over to carb. I went on FordMuscle.com and found a little information but you have to subscribe to get more information So Please let me know. Thanks

 

I also have a E4OD so will i still need a computer from a 87-93 mustang?

 

What's your SD system doing you don't like if I might ask?

To convert your truck to MAF your best bet is to find another mass air truck with the E4OD and pull the engine harness, MAF meter, and computer. If you go the Mustang route you'll need a seperate tranny controller as well as the engine harness, meter and ECU.

 

I'm sorry to hijack a post, but is this even a remote possibility? I could see big benefits for a guy like me, stranded without a shop that can/will work on my vehicle and having to beg guys on the internet for help (which I appreciate more than you'll all ever know). I don't get any better gas mileage (maybe even worse), than my dad got with a 73 f250 without all the junk (normal carb, and ignition system). I would be able to work on and understand my own vehicle, etc, etc.

The reason why i dont like my SD system is because i have to worry about how i mod it. I really want to port polish, gasket match and i cant do that. Sure i can put the crane 444232 camshaft in and long tubes and call it a day, but if you know me i cant stop there. I need more. dave2 you can switch to carb, im not 100 percent sure how so i cant tell you wiht misleading information. I was thinking about doing that but then i thought about gas milage, if it would drop, and also cold weather starts. Im sure it wouldnt be bad with an electric choke but i eventually want to do some trail riding and dune climbing and the EFI would be the best choice for me. I also like the quick respons from the EFI.

 

Who said you can't? Sounds like you are getting some bad info. The ONLY requirement you must have to keep the SD computer happy is a steady vacuum signal, you can build the motor to flow as much air as you like and the computer will happily drive it*...as long as it's within the supply limitations of the fuel system. The cam determines the stability of the vacuum signal, it's got to be 114deg LSA or greater and no more than 216deg intake duration at 50 thou.

That cam is good, but it's a poor choice for your motor since it's already got a roller cam, and the Crane is a flat tappet. Plus it's not giving any more lift than a set of 1.7 rockers on the stock cam. Get the Comp 35-349-8 and a set of valve springs, and keep the rest of your valvetrain.

* The stock computer maps will also limit the total amount of power produced. Generally there is enough adjustment range to max out the stock fuel system at about 300hp. Beyond that the fuel system would need to be upgraded and then a tuner used to modify the computer maps accordingly. The bottom line is there is no limit to the amount of power you can make with an SD system as long as theres enough fuel supplied and the computer has accurate numbers to work with.

 

Acually i thought that you couldnt get that much hp that you just said without converting. I know anytime u add tons of hp u need to add more fuel and air. I just dont want to worry about that stuipd computer. But id be happy with up to 300 hp in a bronco. Better than the 1 something they make stock lol.

Then i dont have to worry about getting 1.7 RR or should i still get those? Thanks alot for you help man.
