New motor ... Will it work?
Ok, she's a 1986 f150 efi 302, the motor is a little tired. It's not burning oil or anything but the bottom end is making some noise . So I have a good buddy that works at a junk yard, he found me a 1988 lincoin mark vii motor with 70,000 on it. They want 575. So I'm thinking of doing it. Now if I change all my Vbelt stuff over to it and my exhaust manifolds .. Will there be any problems? I have a fresh t18 with new luke clutch will the fly wheel be the same? I Also herd I have to use the lincoins dizzy. Is that true? willmy speed dencity be ok with the diff motor? I kno lots of questions but I just want to make sure this motor swap will be a weekend gig and that's it. I appreciate any feed back. Btw I plan on doing all the gaskets when the motor is out

Strip the Lincoln motor down, take all the wiring and the sensors off it, and the intake. You will also need to swap oil pans. Then put all your stuff on the Lincoln. Your old sensors, wires etc.
About the dist; Check the firing order on your engine, and check it on the Lincoln. They should be the same. If they are different, the Lincoln may be a HO motor. No problem, just move your wires around to match the Lincoln. I would use the truck dist, but you will need to do some research on the Lincoln dist. I see no advantage to using the newer dist, unless it has a remote TFI mount. If it has the remote TFI mount I think it might be an advantage to try and use that if the wiring will work.
While you have the pan off, check the timing chain with your finger. If it's loose, you might as well tear the front of the engine apart while the pan is off and change out the timing gears and chain. The Lincoln probably has the undesirable plastic top gear anyway.

Of course it will work. It's pretty much the same engine once you change over all the accessories like Franklin2 says. I would inspect your truck oil pan carefully before reuse. Some of these pans had a tendency to rust out. Hard to believe, but I've had it happen to me!
Something I have wondered about truck vs car engines. Now this goes back to pre EFI and roller cam days, so I may be out of date, but I had noticed a difference in connecting rods between car and truck engines. Cars had the broach cut connecting rods with the square headed bolts and trucks had the spot faced rods with the football shaped rod bolt heads. Spot faced rod bolts were stronger and were used in Boss 302 blocks. Now, I would not let that stop me from using a car engine in a truck, but I would expect shorter life, particularly if I was using a truck like a truck. If I was doing a new engine build, I would use the truck rods as a lo buck upgrade.
