94 Mass air ?
I found a 1994 f-150 xlt in the junk yard that I have been able to get a lot of parts off of and I noticed that it has a mass air 5.0 in it,I thought mass air didn't start until 1995 and the build date is 8/93. The truck was a clean one until it got hit in the front. I wanted to get the block to replace my 5.0 efi in my 86 what if anything should or could I get off of it to help me change over to mass air. The computer is there but it has the electronic od trans and mine is aod,so that won't work,I want to get the rear too but don't know if my drive shaft will fit the yoke as the new rear has a vss in it. Can anybody here tell me if what I want to do will work

Mass air F150s were hit or miss in 94 and 95, with all F150s being mass air with OBD-II in 96. If you are going mass air, grab as much of the wiring as you can. It is a good bit different than the 86 wiring, but you should be able to steal what you need (sequential injector harness is the biggest) from the 94 harness and add it into the 86 engine wiring harness. The automatic mass air computer will run the engine without the electronic transmission being present, so it would probably be wise to grab the computer too while you have the chance.

I will see the owner of the junk yard on Monday and get a price,I hadn't planed on switching to mass air but I will as long as I can get everything on the cheap end I might as well do it and then I will have a better choice in cam shafts.I was still under the impression that I would need a computer from a manual truck or a c6 to make it work right.
Anybody know if the rear with vss will work in a truck without.

It should work OK, the companion flange may need to be changed to fit your "U" joints if yours is different.
Do not worry about the vss in the top, just leave the sensor in there to plug the hole with no wires attached.
It is more than likely a 3.31:1 ratio 8.8 rear end.
What do you have now?

Also the 94 PCM is a CCD computer so make sure you get the Black ICM off the fender also as they changed in 94 from the old "push start" to the "CCD" Ignition system.

Check the tag on the rear end out of this truck or the door info, as I said it maybe a 3.31:1 ratio rear end in that 94 truck.

well lets talk about this a little bit, 1st noone has metioned that mass air in a 94 fseries was a california emmsions vehicle, so being in nj i can see why it would be there, it wasnt hit or miss, cars in that era were differnt as if it had to have the cali emmsions std it was either dis, or mass air, tbird/cougars are another liek that. the trucks and vans as well. . more than likely if that truck has a electronic overdrive it will have a 3.55. i would persoanlly go witt a 3.73 as its alot more fun and moves the truck a whole lot easier

I forgot that Cali got the mass air first that must be what it is,and it does have the e4od trans thats why I figured it would have 3:55's in it also,for the price I can get it for I will take the 3:55 rear with the limited slip and at the very least I can do a gear swap later I just want to find out if it fits the stock driveshaft in the 86.My 86 uses a two piece shaft maybe the back half of the 94 would work if mine doesn't fit or at least my yoke might be able to be used on the 94 rear.

First off I have never saw a ford pick up with a 3:31 rear no matter of the year and most standard rear that came with a E40D electronic tran was a 3:55 and a 3:73 as a option,and as far as mass air 95 & 96 were standard no matter if it was a 5.0 or 5.8 and California had them a year or two before.I simply forgot that California got them first and to find one in a NJ junk yard is odd,I think I am going to try and get the whole truck and strip every thing I can use and give them the cab,bed and frame back to scrap.

In 95 only the California 5.8 had Mass Air. The 5.0 had Mass air in 94 & 95 in all states.That is why the truck in NJ has Mass air because all 94 trucks with the 5.0 had it that year.
