460 EFI MAF conversion
#17
Has anybody figured out how to tell the computer crank location. 5.0 dist has a shutter wheel to give computer crank signal, does the SD 460 have the same?
If not how do you convert dist to provide crank signal?
To get around the computer programing, you will need an interface like a tweecer or mega squirt.
Need these to reprogram 5.0 computer to fire in the 460 fireing order, and other tasks associated with firing order, ie fire injectors, spark, timing etc.

Thanx Conanski, You seem to be pretty knowledgable so I have another question. Just to refresh i have a 1997 F350/w a 460 non maf. I have installed a set of timing gears for a 1968-1973 (I believe those are the years) 429 interceptor which really "woke up" my 460. I wanted input or advice on going to maybe a 30# injector and a larger throttle body. How will this affect motor performance without having a maf sensor (remember mine is speed density). I also want to replace my cylinder heads with a set that breath better, but the only ones Ive found so far are a napa brand and Im still researching them. Thanx again.
Please clarify. If I can change up the timing gear set and get a nice performance boost I'll order them up asap. Any suggestions on which set to get?

I thought the 96/97 had the better timing gear sets already?

I think all the EFI motors got a straight up timing chain, 88-97. These things are old enough now that you never know what has been done to them though. The "early timing chain" thinking could have mistakenly put a 72-86 (or whatever years got the retarded stuff..) on an EFI motor that already had the good stuff. Just sayin..

The 88 up EFI 460 engines all used the same straight up timing chain that came on the 68-70 engines. I spent some time researching this when I built the 89 460 EFI for my truck. Putting a new chain on an old engine will always wake it up because the old factory chain will be stretched. The new chain advances the cam back to where it was when new, so it will run noticably better.

I have a MAF 460 in my '78 F250. The 460 dist. has the mounting boss and holes for the TFI module. You have to make a hole in the dist. to allow the TFI module to plug into the trigger under the cap. I used mustang parts for this, everything bolted in. I can take a picture of my set up if anybody wants it. I used a painless harness and an A9P mustang computer. I replaced all the sensors on the motor with ones for a mustang. You kind of need to make the TPS fit, but everything else bolts right on.
I have 36lb injectors on mine with a 75mm PRO-M MAF. I have heavily ported E7 heads, with a custom ground comp cam, roller rockers, 10.5:1 compression and the whole thing is balanced.
If you run a MAF, you will need the y piece from the intake of a MAF F-150 or Bronco, I got mine from a pull a part for a buck. If anyone has questions on this conversion let me know. I spent a bunch of time figuring out a lot of this crap, I would like to save people the time.

ECU number
Does anyone know the ECU # of the California, 460, E4OD? I own a 94 and am looking to convert my truck to MAF. Will the California computer simply plug and go (after a harness overlay and mass air install of course)? A close friend of mine is NMRA racer and has a few 9AL's lying around. If I go the 9AL route, what are the options as far as trans. managment? Is the 460 Caly computer as easy to modify/upgrade as a mustang 9AL?
This is a project that I am definately going to do. I have access to a dyno (racer buddy) and will do a before and after to document any gains or losses. Not looking to build a neck breaker. Just breath new life and personal interest back into my truck.
Thanks in advance for any guidance.

DUDE WFT ??? I live in CA and i have a 1994 f-350 4x4 super cab my truck doesnt have mass air ?? it was made in canada i know that <-- means it was build well eyh .ah ha
But seriously wtf ???
you guys said in your post mass air came standered in ca
SO is my truck set up for mass air and i dont know it ?? and all i gotta add is the sensors ? thanks
