ho firing order

The HO engines should have the Marine cam shaft and use the 351 Firing order, have a double roller timing chain set. the 4 barrel Holly's were modified to be able to run thru the entire govt smog test on only the front 2 barrels. carb rework can help somewhere I have the Holly Mods recomended by a Ford Engineer.
