HO came out in 82, roller cam in 85, and fuel injected in 86.

HO stands for High Output, mustangs have them. F-150's have the normal 5.0

maybe intake?

and yes what makes the difference in the firing is the cam. thats usually the easy way to tell what firing order to use is if you have a non roller or roller cam.
