I just put a 96 Explorer 5.0 H.O. engine in a 91 Crown Vic which originally had the non H.O. 5.0 engine in it. And it is running a little rich but thats seems to be working itself out. The car still has the original non H.O. computer in it which and I just rewired the injector wiring harness to match the H.O. firing order. But is there another computer I should be using? and might this running rich problem have anything to do with my using the stock/original computer? I'm wondering if there is anything else to check with this swap?
Also, does anyone know if late model Mustang wheels will work on this Crown Vic without using spacers?
