Ignition Firing Order On
Ford 5.0L HO (High Output) Engines
There seems to be much confusion about the firing order on Ford 5.0L HO (High Output) engines.
Contrary to the plain 5.0L engine, the HO (High Output) version uses the same firing order as the 5.8L engine. This is probably the case because early 5.0L HO engines used a 5.8L marine camshaft.
The firing order for the standard 5.0L is: 1-5-4-2-6-3-7-8. The firing order for the HO engine is: 1-3-7-2-6-5-4-8. The rotor inside the distributor rotates counterclockwise on both engines (see illustration).
Using the plain 5.0L firing order on the HO engine does work, however the engines will have low vacuum and very poor idle. At higher rpm it appears to smooth out, but is very low on horse power, not at all what the customer will expect from this potent power plant.
