Engine Swap
I have a 1994 f-150 with a 302. I have the opportunity to get a 5.0 HO out of a lincoln mark VII and was wondering what all would need to be done to make the swap. The car was given to my brother cuz the tranny is shot, but the motor is supposed to be pretty good. The guy my brother got it from is a pretty good friend of his and says the motor never burned any oil.
My pickup has 207,000 miles and in deep need of a rebuild and now this comes along and hopefully will work out for me. I know the air cleaners are on opposite sides of the motor, different intake, and the care has one throttle body and my pickup has dual throttle bodies. Can the intakes just be swapped or would I have to fine a place to route the air cleaner to?
Thanks,
Matt

I just did this exact swap on my 90 F150. The biggest problem is the computers. I put the truck intake. The difference is my truck has bank injection so my computer was shooting gas into the open valves since the cam is for multi-port. I splice the lincoln computer into the truck harness. It works...sort of. It took a professional tech about a week of looking up wiring harness and trial and error. It runs great except for the idle surges like crazy, my gauges, tach, and cruise no longer work. This can all be avoid by putting a truck cam in the lincoln engine along with the inake. I knew this going in but wanted the roller cam. Also didn't realize how hard it would be.
Good luck.

This has been done lots before. Get the motor, strip it down to the bare longblock, and then put the truck intake, oil pan and pickup, distributor, and accessories on it and drop it in. Use the truck computer, sensors and wiring, the motor will run fine. Be sure to use the HO firing order on the plug wires.

Oh man, I miss my Mark VII. Ironically, I sold it to a guy who wanted the engine for his F-150...

Ok, sounds like it is doable then. How do I figure out what cam I have so I don't have any problems with that? Obviously I am probably goin to lose a little power putting the pickups intake and computer on the HO, but all i really want is a decent motor that I can trust. Would i use the pickups injectors as well?
Pickup is a 94 and the Lincoln is late 80's or early 90's. I'll find out for sure tomorrow.

From what I understand, isn't the truck-style intake actually BETTER for flow? I kinda figured the only reason they don't put it in the Mustangs (or similar Hi-Performance cars is hood clearance...
Someone correct me if I'm wrong on this, 'cause I'm actually quite curious about it now.

Another guy here dyno'd a HO motor with both the car and truck intakes, and the truck intake made more HP. The truck intake certainly has the bigger volume runners so this would seem to make sense. Still I'm not totally convinced the truck intake is the better choice for a 5.0 motor in a truck. The larger volume runners hurt low rpm air velocity which is directly related to low rpm TQ, and anybody that has driven a 5.0 truck will tell you they are weak under 3000rpm. The car intake with a 1" spacer between the upper and lower is probably a better match.

Well I went and grabbed the car today and let it warm up. Brought it home and noticed a check oil light, so of course I checked it. Ended up dumping in two quarts to get it full. I haven't had the chance to look under it to see if it is leaking oil or not. Hopefully that is it and it can be fixed during the swap. If no leaks I'm gonna do a compression check to make sure there's no major problems.
The car has 134,000 miles on it, so I'm not really sure what to do yet. I could rip into the motor and do a rebuild or just put it in and see how it does.
