I am having trouble figuring out the firing order for a ´90 Ramcharger. The manual says it is 1 8 4 3 6 5 7 2, but it keeps misfiring badly. I am normally a Ford guy, and this is my first Dodge, and I must say after a month or so, on more than one occasion I have been in for a rude awakening. This is a nightmare! If someone else has a different firing order, please let me know so I can try it out. thanks! shasten

 

That's the right order, same for big and small block, but the cyls are numbered different than a Ford. Might be what's throwing you? 1,3,5,7 are on the driver side 2,4,6,8 on the pass.

 

I agree,
Ford

4 8
3 7
2 6
1 5

Dodge/GM
8 7
6 5
4 3
2 1

I had figured out the piston numbers, that is not it. i think whoever rebuilt this engine did the reverse timing and put the firing order backwards. I know that works with Ford and Chevy, and I imagine that it works with Dodge as well. Not really sure. I don´t have any clue as to how one figures for that. I know the wires into the distributor would change, but how to figure for that--I don´t know.
