Swapping engine in F150
Hello everyone,
I have a 87 F150, 4 speed manual with the granny first gear. It has 5.0, not sure how many miles, but after failing my emissions test I located a 96 explorer 5.0 with gt40 heads and was completly torn down and was honed, journals polished, and complete engine gasket kit. The builder also put new rings inthe honed cylinder holes. I am going to use my truck intake and I located a mountaineer with same 5.0, which I took all of the front brackets, pulleys, fan and fan clutch with fan pulley.

Your opening statement is a first for me "but after failing my emissions test I located a 96 explorer 5.0 with gt40 heads" Why replace the entire engine just because you failed an emission test?
Assuming there is a logical reason for replacing the entire engine it looks like you have most of the bases covered. I'm sure there will be some minor little doo-dad piece that will hold you up, at least that is what usually happens to me. Good luck

Yeah its EFI and, from what I have read the truck intake is much better than the mass air throttle body. Did I mention that I pulled the serpentine assembly from a mountaineer at junk yard, which they had only one. Got lucky. Sine timing chain cover is different from water pump design. I was going to do the heads only, but I found the whole engine that was partially rebuilt, for same price. Thanks for input will keep you updated. Thanks

I took off the maf explore intake, 96, and was just going to swap old block, heads, except efi intake, bolt in new rebuilt 96 5.0. block w/gt40 heads. Then bolt on original truck intake, new msd distributor, new wires, but should not need any computer mods since using original truck intake right?

They are the three-bar GT40 heads? Three vertical lines on the front? If so everything should bolt up. I'm doing the same thing with a '98 Exploder engine. I've already swapped the oil pan and pickup tube, timing cover and water pump and intake over from the old motor (and heads, but that's another story) I'll be swapping the distributor and accessory brackets from the other motor over, as it's just easier in my book. The Explorer front drive was odd and uncommon, I'd stick with the truck stuff, you can't mix and match as the explorer pulleys are sucked in tight toward the engine, so it has to be all or nothing.

Yeah, I got lucky and was able to find the entire serpent, system fan, fan crutch, brackets, and pulleys, from another motor. I know that its tighter, to engine but cooling is supposed to be better. I am just about ready to swap. Thanks for the comments and will let you know outcome. I am lucky to have two in laws who are mechanics, but convincing them it will bolt up isn't easy, lol.

What makes you think it will pass emissions now if you're keeping the same sensors, injectors, cat that your truck originally had?
It's also going to run very lean on the top end since the Explorer engine makes nearly 30HP more, and your computer will have no way of knowing that.
