Firing order. The HO has the same firing order as the 351W.

82' was the first year for the H.O. which meant more radical cam timing, a double roller timing chain, a dual inlet air cleaner, and traction bars.

ORIGINAL: bobby

5.0 is not roller 5.0ho is i think

It depends on the year Bobby, cause I got an 89 Marquis motor for my Brocno that is roller. My original 93 bronco motor was alos roller.

Difference between HO and 5.0L more horsepower and firing order. Then again in the later F-150s had a HO firing order.

The main thing between the Ho and non Ho is the cam.Yes some have rollers and others don't.Thats what makes the firing order diffrent.I am auctually running and non HO motor at the moment while rebuilding my HO.

I dont think HO has to do w/ the rollers, i have a HO(completly stock) w/ cfi [:'(]. not sure if it is the roller block or not but I do know there is no rollers.
