90 Lincoln MK VII is not speed density- it's mass air. My donor was an '89 MK VII, and it was mass air. Don't know if this makes any difference- probably not if you are keeping the truck injection and just using the Lincoln block.

I know that when you run a manual transmission, car and truck flywheels are different diameters. IF the same goes for flexplates, you're going to have to run your truck flexplate on the 302HO. Now, IIRC the 1986 f-150 uses a 28oz flexplate while the 302 HO uses a 50oz flexplate. This means IF the flexplates are different diameters, you'll have to find a 50oz flywheel that fits the truck transmission.
BUT, if the HO flexplate and the 302 flexplate are the same tooth count, ignore everything i've put up here.
Just figured i'd give you a heads up since i know a guy that put a 28oz truck flywheel on a 302 HO and promptly wiped all of the bearings out of it.
