    I got a Bronco at work that needs a motor. It is a 351 that lost its oil pump. I got a new(er) motor out of an 87 Grand Marquis. It is fuel injected, but im gonna put the carb, intake, and exhaust manifolds on the mew motor. My question is, how involved of a project is it? Ive really never done a motor swap entirely by myself before. Ive pulled a bunch of front drive motors before and I know thats easy. I have never done a motor on a 4x4 truck before. How hard is it?

    Thanks,

    Tony

    need to take the intake and exaust manifolds plus all emissions equiptment off the old motor for the new one,plus oil pan and pickup tube,motor mounts,flex plate for auto,and anything bolted to the old motor for the new one.make sure the new motor has a fuel pump mount in the front cover that can be used,not cast shut.

    best idea is to buy a new oil pump,fuel pump,water pump,plugs,cap,rotor,wires,valve cover gaskets,and anything else that is bolted on and change them out now so you dont kick yourself later on for not doing it,since it will be easier doing it now when the motor is out and swinging.

    did a few engine swaps on fords,this is just a few things to watch for.the exaust and intake manifold ports make sure the gaskets cover the ports.had a 4 cyl that didnt,pulled my hair out till we did the ether test and found out the problem why it wouldnt idle.the fuel pump mount in the front cover is important,since you are going from fuel injected to carbruated,sometimes they dont machine the hole in the timing cover,plus check to see if they put the excentric on the cam.

    I agree with Clueless.:nod:
    You might as well freshen it up while it's out and on the stand.:waving:

    There's other stuff I do too to freshen it up on an engine change.
    I put in a rebuilt torque converter and replace the rear main oil seal while it's out. Disturbing these two parts a lot of times causes them to leak later. They cost a bit to replace but your will not have to go back later. If at all replace the seals on the converter so it don't leak.

    Finally done and running. I hd a hard time getting the motor out due to its body lift. I had to take off the oil pan and get the chains real close down on the motor to get it to clear the core support. The core support was welded to the fenders by some genius who replaced the body panels and I couldnt get it apart without cutting it. The reverse was much easier than the removal.

    Thanks,
