[87BOSS351C]

Here's the deal; I may be trading my snowmobile for an '85 Mercury with a non-HO 5.0 (plus a 351M and a 460). The engine has a slight knock, but I am mainly interested in swapping the Fuel injection over to my '72 Gran Torino (which has a stock 302). It is my understanding that the non-HO's use the traditional 302 firing order. The main ?? is, my '87 mustang still has the computer in it, would that work with the non-HO system and give any benefits or would the different firing order cause problems? For a stock engine I image the merc computer would work best, but it never hurts to think out loud.
