I bought this e150 and was told previous owner put a 351 windsor but went to change the air filter and had to use the 302 filter size. Main ? is where can I find out the real engine and transmission that is installed? Also The wiring has been damaged and I have to find out what the third wire in my coil harness is alnog with a few underneath the dash that are dangling. Main concern i s the ID of what I got and what I need.

 

If it runs fine check the firing order, they are different.
302 = 1-5-4-2-6-3-7-8
351 = 1-3-7-2-6-5-4-8

If he switched engines he more than likely used the old air system and it would take the 302-air filter.

 

If the thermostat housing is behind the water pump and the bolts are hard to get to its a 302. If the thermostat housing is above the water pump its a 351w. If the bolts to the thermostat housing are vertical its a 351m.

 

I also wish to ID the transmission along with the wiring shorts in the engine area, I was told to connect the cut wires, which would be a good solution. I just have a fusibvle link to replace, dont know which size. I also have some 1=2 wires danglining from the fuse box

 

I would think if it has OD it would be an AOD, you would need to look at the shape of the pan. If you think it is a stock transmission the you could use the door codes.
I might be able to email you the wiring diagram for a 1983, as it should be the same as long as you do not have FI.

 

Okay, you're going to have one of four transmissions either a 3 speed (P R N D 2 1) which would be a C4, C6, or FMX, or a 4 speed which would be an AOD (P R N OD D 1). I'm willing to bet that's it's a c6. Look at the tranny pan, if it's a square with two angled corners then it's an AOD, if it's more rectangular with a notch in the one corner then it's the C6, if it's a square pan with 11 bolts it's a C4, if it's a square pan with 14 bolts its an FMX.. The FMX or C4 should not be in the van, but if someone has swapped in a different engine then it's also possible that they swapped in the tranmissions too.

 

Cool, I love this info better than looking for a stammped plate. The only thing left is the carb, if I got the 302 air assembly is it pretty good intuition to think it is the stock carb?

 

No but if it still has a tag under the screw on top then post the numbers and we will get back with you.

 

The drive stick states P R N D D 1

 

You have an AOD.

 

Well on that theory that "if they swapped the engine they may have swapped the tranny too" then AFAIK they can use the same steering column with its 6 shifter positions. So it could be using an AOD column but it's going to a C6 and the shift position labels don't tell you anything.

 

The thermostat housings bolts are parallelel to the ground above the waterpump, so I get that previous owner told me right it's a 351W. I hope he told me the truth that it is bored 20 over? What exactly is 20 over?

The transmission does have more than 11 bolts and it is square. the rear corner angles are not at 90 degerees. I take that to be an AOD. Question, What do I tell them at the auto parts store about the transmission? AOD?

Thridly but not lastly-the carb. No tag on the bolt but fuel filter is passenger left, front , bottom with the throttle linkage on the driverside(maybe always). Distributor vacum is directly centered in the front. I really thank you guys for the input and wish you many more.

 

Ok, you have and AOD. When you ask for transmission parts tell them it's an AOD for the transmission. That sounds like a typical motorcraft carb and duraspark two ignition. On the drivers side of the fuel bowl there is a number stamped or molded into the carb. It will be 1.xx. If you look in the "Fuel injection and carburetion" forum there is a sticky that will tell you what size carb you have I.E. 1.21 is a 354 CFM.

 

ty all. I just want to state at this time I need to clarify That my concern about the 20 over measure is either a next size ring spec or some other measurement. I really dont need an answer cause now I am trying to figure out the AC. I guess that is another section. Thanks again! and oh yea see you in the AC section, LOL.

 

20 over is that the cylinder bore is bored 20 thousandths of an inch over standard.
