5.8l engine swap
I'm a diesel guy, and I've hardly got any expertise with gas engines. I hope ya'll can help me with a gas engine question with the OBS.
I'm working on a 2wd 1996 F150 with a 5.8l EFI and E4OD. The engine is bad, apparently blew the main bearings. I'm looking at buying a used running junkyard motor to swap in and get it back on the road.
I've got a line on a 5.8l from a 1994 E150. Its listed as MFI (I guess that means Mechanical Fuel Injection, ie carbeurated?) What would it take to swap this over? I guess I'd need to swap my throttle body over at least. Will it work at all? Any year-year differences I should be aware of?
I'm grateful for any help y'all might give me here. Thanks!

Pull the engine out of the van, assuming that it's a runner, pull the intake manifold. Put the Intake Manifold and Exhaust Manifolds off of your F150 onto the running engine. Stuff it back in there, and hook everything back up. The long blocks on these motors are identical. I don't know exactly what intake or electronic differences there are between a '96 F150 and an 94 E150, but I *think* all of the 1996 F150's were OBD-II and Mass Air setups. I don't think the 94's were.

MFI= Mutlipoint EFI. All that means is the engine control system is Mass Airflow (MAF). Easy swap. You need need to swap the misfire detector sensor and balancer w/stator from the 1996 engine onto the donor engine. You also need to swap the EGR tube, valve and DPFE sensor (and silicone hoses) from the 1996 onto the 1994 donor. Truck exhaust manifolds most likely as well.

Great, thanks for the input! The engine from the van is (allegedly) a runner according to the junkyard, so I will keep looking into it. Recommendations of how I should check it out before I buy it? I planned to at least spin the crank by hand. Junk man says he'll pull it when I pay for it, so I guess its still in the van.

Well, I called the junkyard back this morning and they told me they would not let me inspect the engine before purchase. That's a hard pass for me! So I'm back to looking. What range of years on the 5.8l will interchange with mine, with simple modification like the manifolds?

Vapor Management Valve (VMV). A 1996 F150/Bronco does not have a Canister Purge valve (CANP). It's a one year only item for this vintage truck 1996 (OBD-II). Yes it provides the same functionality but you cannot swap one for the other.
