YES the intakes will definately interchange. I guess if you're a driveability tech, you already know all the wiring and return line stuff, but if you didn't, I just thought I'd throw that in. There are several stand alone wiring setups out there to use.

It will work. The son of the guy who owns Painless Wiring, Lance OVerholser put a EFI intake on a 289 engine in a 2 door 64 galaxie and drove it from Texas to Indiana.

Unless the Linc engine is blown or needs serious work, grab the whole motor. Your '72 302 will have the wrong firing order for the EFI, so you'd have to change to a late-model cam. The '91 will be a roller cam motor, better heads for unleaded gas (probably flow, too?), and totally set up for EFI. Guess it depends if you've got a lot of $$ into the '72 motor tho.

The 91 Lincoln still uses the old 302 firing order but I doubt that the camshaft in the 1972 302 will be compatible with the speed density computer.

I'm not so sure on the speed density. By design, the mass-air has a little more "give" in modification. I'd grab the engine harness, and the ecm for sure. If you are interested in getting rid of any brake parts I might be interested.

86-95 Mustang (89-95 Mass Air)
91-92 Cougar / T-bird (Mass Air)
96-01 Explorer (Mass Air)
86-90 Mark VII (Speed Density)
1-5-4-2-6-3-7-8
86-91 Crown Victoria, Grand Marquis and Town Car (Speed Density)
86-90 Cougar / T-bird (Speed Density)
1-3-7-2-6-5-4-8
86-95 Mustang (89-95 Mass Air)
91-92 Cougar / T-bird (Mass Air)
96-01 Explorer (Mass Air)
