You can tell by looks or by the VIN number if the engine is original.
The fifth digit could be H or Q. H is for the Windsor engine and Q is for Cleveland. The Windsor looks like an ordinary 289 or 302 engine, the Cleveland is a big head 400 version. I don't think they used a 4bbl Windsor but they did use a 2bbl Cleveland so that is not a good example.
5.0 HO and 351 Windsor share 1-3-7-2-6-5-4-8 firing order
When looking into the engine bay the number one cylinder should be on
your left hand side (left bank) at the front of the engine. The number
eight cylinder is on the rear right (right bank) up against the
distributer turns counter clockwize (#1 should be labelled on cap)
Take the cover off the engine, there you will view below you three coils, disconnect the wire from the middle one only after disconnecting the battery, disconnect the wire harness to that coil, remove the not securing that with a 5/16 socket trhen pull straight up, replacement is opposite removal.
There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps
