I have this truck and we have done the 18436572 firing order but we cannot get it to fire yet we are at tdc and it seems like the rotor is in between the 1 and 8 on the distibutor cap we have reset the timing several times already and it still won't fire if you can give me any info I sure would appreciate it.

Firing order is right. Did it run before the timing got messed up? What happened? The more dtails the better the diagnostics

It can be a 292 6 cyl, 350 V8 or 454 V8. (Unless someone swapped in something else.)

292 - 1-5-3-6-2-4
350 and 454 - 1-8-4-3-6-5-7-2

Number one is the front drivers side cylinder.

I changed my plugs, but I may have gotten them out of order. I tried to pull one and replace one, but I had taken off two, before I decided to go one by one. I just want to make sure they are in the right order.

The firing order is 1-8-4-3-6-5-7-2 the number one position is 11:30 on the distributor cap. That's looking from the driver's seat. The distributor turns clockwise. That should get you going.

That means either the timing or the firing order is wrong.

Did you have #1 cylinder on tdc of compression stroke before you pulled the distributor? Put the #1 cylinder on tdc, look to see where the rotor is pointing. If you can blow air into number 1 cylinder, its not on tdc or something else is wrong? You can use a fuel line hose that will fit snuggly in the spark plug hole, try to blow air into cylinder. There are other ways to check that.

I found the above picture. If you put the number one cylinder on tdc of the compression stroke whichever plug tower the rotor is leading into, should be the number one plug tower.
