I was just wondering what the firing order is on a 91 mustang lx 5.0. I have been looking and Im mixed up because I seen two different firing orders for the 5.0. Thanks for the help.

you've see two different firing orders because there is the 5.0 and then theres the 5.0 HO. It makes a difference

302= 1-5-4-2-6-3-7-8
302HO = 1-3-7-2-6-5-4-8

pull the cover off of the intake and if it s an HO it will be stamped inside the cover plate, held on by 4 screws
