the H.O. 5.0 is the one found in mustangs. nless your engine came out of a musntag, you dont have an H.O.. as far as firing orders are concerned, i dont know if theyre the same, but the order for the truck 5.0 is 1-5-4-2-6-3-7-8. hope this helps, good luck!
if you find a mustang cam you would prefer, you can put it in & change the firing order to correspond. the crank and pistons don't change.
the 302 in my 95 F-150 fired 13726548. The reason stated was 1 then 5 that close put too much strain on the front main bearing.
redlariet - I don't really want to change the firing order, but I'm shocked to find out that I can! How would I do that? I would have to change the crank, unless I'm missing something, becuase the pistons reach top dead center in a certain order dictated by the crank, right? The reason I'm interested is that there are hundreds of mustang cams, and like I said ONE for mine in the Crane catalog. I would like to read anything you have about changing the firing order. Thanks.
the pistons are in the same position with either firing order--ie, 3 and 5 are next up after 1, on the truck 5 is on compression and 3 is on exhaust. the different cam would put 5 on exhaust and 3 on compression because of when the valves open & close. the fuel injection is not sequencial in the truck so that's not a prob. hope that clears it up.
