Hi all. Been awhile since I posted anything. I have a ‘94 F150 with a 5.0l and e4od. I’ve done a few things to it and had to fix a few things but by and large it’s just been a reliable old truck and I love it.
At 345k miles it’s starting to get a little tired so I’ve started trying to figure out how to keep it longer. I ended up picking up a 5.8 and my 16 year old and I are planning to do a simple rebuild and swap them out. I’m, I’ll probably throw a little cam in it, some headers and maybe do something with the heads. If you guys want I’ll try to keep a thread going about it.
So far I have the trans separated and got the engine on a stand. Found my first few oddities.
Most notable is the casting number. The block is missing 2 casting numbers, stamped F E-1650-AA. I searched on the Google machine and could only find two other mentions of this. One suggestion was perhaps the mold in the casting broke. The other thought perhaps it was either a replacement block or started as a marine block. The exhaust manifolds have the F4TE cast and the block. There’s also a sticker on the fuel rail with an F4TE sticker. I’m assuming it’s an F4TE block but won’t know until I get it open. So we’ll see.

More than likely, it is a replacement block from ford, wasn't produced in production for anything in particular.
F - 90s, E - Engine.
A production block for a 94 Truck would have the 4T.
Under intake should have holes drilled for the roller lifter spider retainer, it is roller reader.
Be aware, if it was a marine application, it could be counter rotating assembly.
Ascribing to the idea that it’s a replacement block, my guess is that they pulled it of a truck with an F4TE block, swapped everything over and put it back in. It was cut out of a rusty plow truck so unfortunately I don’t know for sure what it was. I won’t know for sure until I get into it but should be fun to find out.
The other oddity I’ve found so far is the intake has one tube instead of two, implying that someone had swapped it to maf at some point. Also, aside from the EGR valve and an idler wheel where the smog pump should be there’s no evidence of any smog equipment. There’s no crossover tube between the back of the heads, and no hole where a tube could have once been. No plugs. They’re definitely ford cast iron heads, just not sure which ones. Again, once I get into it I’ll find out.

Are you saying it has a single throttlebody intake on it? Got any pics?
P.S. If it was from an F250 or bigger those trucks had a different air injection system... it went into the manifolds instead of the heads so no crossover tube.
I didn’t know that about the 250s. I did google the F4TE part number on the manifold and noticed the tubes going up and over. Didn’t realize that was why as the part was listed as generic for the engine. That said it doesn’t have those tubes.
It’s still the same dual throttle body, but rather than the dual tubes that I’ve seen run all the way back to the air box it’s a 2 into 1 such as is on my current 5.0.
not the best picture but I’ll attach one and I can take a better one tonight when I get home.
Got some more pictures. You guys tell me what you think.
No smog pump Throttle body Coolant lines into the oil filter adapter? Missing smog solenoids. I don’t even see where there should be connectors for them Back of cylinder head. No smog holes?
Weather warmed up some so I’ve been able to start tearing into it ever so slightly. Understand between work, living on a farm and 5 kids my time is a bit limited. That said, last night I got most of the front stuff off the engine. Hopefully this weekend I’ll get all the “other stuff” off. I’m looking forward to cracking the heads open and see what kind of condition this is actually in and how useable the block is in its current condition.
i have determined (I think) that it has to be a ‘96? Last night I removed the crankshaft position sensor. From what I can find that was only on the 96? I assume this can go into my 94 truck and just not put the sensor on?
Looks like a 1996 5.8L engine from an OBD-II truck. The misfire sensor, and the one year only tone ring equipped balancer, is the prime clue. Same for no air injection ports on the heads, and no TAB or TAD solenoid, since there was no air injection used on the 1996 5.8L OBD-II truck engines. The DPFE EGR sensor was used starting in 1995 on MAF OBD-I trucks. You will need the older style EGR tube, EGR valve and EGR Valve Position (EVP) to work with your 1994 computer.
So if it’s a 96 engine, then it should be roller equipped, right? Just trying to think about what parts to put back in when I get to that point. I’m sure I’ll have lots of questions then. It will be a daily driver so I’m trying to decide if I want to look at a cam or just 1.7 rockers.
As for the EGR/smog equipment, from the outset I was thinking I would rebuild this and leave all the smog stuff off. Would it be worth doing this? Seems like it’s not worth buying a new egr when I don’t really even want it. I understand I have to add resistors to the TAB/TAD for my 94 wiring.
Are the cylinder heads any different aside from not having the rear ports? Keeping my eyes open for a set of 3 bar heads but may just stick with the factory heads for now.
