There are three kinds of 302s made from 1982-2001.

5.0L HO This engine was used in 1983-1995 Mustangs, Mark VII

Lincolns, and some T-birds and Cougars. All Explorer 5.0L engines

are 5.0L HO engines as well. They use the 351W firing order,

1-3-7-2-6-5-4-8. Except for the 1983-84 Mustangs, all of these

engines are roller cam equipped. They use a reverse rotation water

pump and front cover. The 1994-5 Mustang and all Explorers use a

unique front cover and water pump.

5.0L Full Size Car This engine was used in 1982-1990 Crown

Victoria and Grand Marquis. They use the 289-302 firing order,

1-5-4-2-6-3-7-8. Most of these cars are not roller cam equipped,

however sometime in the early 1990s they started using roller cams

but retained the 302 firing order. They use a standard (clockwise)

rotation water pump and front cover.

5.0L Truck (except Explorer) These engines are similar to the

Full Size Car engines, except they use different intake manifolds

and camshaft profiles. They also use the 289-302 firing order,

1-5-4-2-6-3-7-8. They also began using roller cams sometime in the

early 1990s. They use a reverse rotation water pump and front

cover.
