1986 Ford F150 distributor cap firing order? Identify changed out motor.?

I think the firing order and location of the spark plug wires on the distributor cap of my truck are wrong. The motor has been changed out of the truck before we got it. How do I identify the motor in it to look up correct distributor cap wire placement/firing order?1986 Ford F150 distributor cap firing order? Identify changed out motor.?
You should see a tag or imprint somewhere on the block that has a serial/model number on it. It may be hard to find under grease, components etc, but it is the only way to know for sure. If you know any ford guys, they can usually tell you what engine it is and you could find the firing order online. Look for that Tag or stamp on the block!



Ford firing orders GENERALLY, but not always are the same. On some of the high output engines the firing order is different.





I am not talking about your owner's manual. LOOK on the ENGINE BLOCK!1986 Ford F150 distributor cap firing order? Identify changed out motor.?
Look on the intake manifold, sometimes they put them there..



according to this the 5.0 and 7.5 are the same,

for id, on the windsors (302-351) the radiator hose goes into the front of the manifold, on the Clevelands it goes straight to the block, and on the 429/460 it goes to the top of the manifold..
