quote:4. Carefully recheck the Fireing Order of the Spark Plug wires. The Cleveland is: 13725648 2 Wires can be switched and the Engine will still start and run, only Crappy as you described.
I agree with Marlin on this one (and I know you said you checked, but....)
The Pantera Manual I have (the white "Technical Manual", Section 23-01-09) shows two firing orders. There is a diagram and listing that is not correct for the 351C.
The diagram shows: 1-5-4-2-6-3-7-8
The 351C and the Pantera uses 1-3-7-2-6-5-4-8
So I am sorry to be telling you to check what you have already looked at, but I have to say that the manual caught me by surprise....
Good Luck -
