I have a 1994 f150 flare side with a 302. I want to put a 302 HO in my truck that came out of my 95 mustang. Do they have the same wiring harness/computer? What do I need to do to use the HO motor the way it is with that intake?

 

The 94 flareside motor should be HO too - my 94 302 is.

 

It has the same firing order but it's not an HO. Also has a different intake

 

To use the Mustang intake, lengthen some sensor wires, might need different throttle cable, relocate air filter or plumb to the existing, not sure if truck tps and iac will work on mustang throttle body so you might need to figure something out there, also not sure if fuel lines will work with mustang fuel rail so you might need to figure something out there, upper radiator hose will have a slightly different routing and I think a truck timing cover will interfere with the mustang intake.

I've never seen it done and as I made out that list it might be the reason.

 

Use the truck intake. You're moving backwards with the Mustang intake. It outflows the Mustang intake. Thank me later.

Other things you'll need to change: Oil pan, valve covers, timing cover.
