Would it change longtube headers at all? And I understand I would need another oil pan, but would any 351 pan work, or does it have to bemodded to fit ona fox, would there be any need for a different radiator, or water pump, or even front end springs? And would any 83-93 mustang 5.0s have the same firing order? or just the HO version, or are all 5.0s in those year HO?
Oil pan... FRPP has a swap kit for like $120 that includes the pan, pick up and dipstick tube..very affordable and no mods needed..
radiator....bigger will always help but a stock 5.0 radiator will work if its in proper working order.
water pump.....depends on if you go with the serpentine setup or stick with old school v belts....serp-stock 5.0 pump, v belt- whatever you got the engine from...
Front springs.... most aftermarket springs are stiff enough for the swap. B springs and SVE springs (same red springs as CJ pony parts) would be too soft for it IMO..
firing order.....86-95 mustang v8's all had the same HO firing order along with some Cougars and Tbirds....all else had the non HO firing order...NOW don't get that confused with a carb setup. The firing order is all in what cam you have in the engine. The rotating assembly has nothing to do with it...

tri angle valve job = 3 angle valve job...... TRI=3

I have a 84 with a 5.8 in it. We did cut the hood n mold in a scoup but were also running a tunnel ram and alcohol. My father used to dirt track race with me and when his car was done we put it all in a fox body! Awesome fun hot rod. I can get you pics from start to finish! Its a tight fit but shes in there!
