Hello, and than kyou for choosing Just Answer!

Here is the firing order for your engine... You will want to make sure the #1 cylinder is brought to TDC on compression stroke, and that the rotor is pointing to the correct terminal on the distributor cap... Copuld actually point to any terminal you want it to, as long as that is the one that you run to the #1 cylinder.

265, 301, 307*, 326, 350, 389, 400, 421, 428, 455

Again... From the first reply:

You will want to make sure the #1 cylinder is brought to TDC on compression stroke, and that the rotor is pointing to the correct terminal on the distributor cap (this means TAKE the distributor cap off the engine and LOOK at where the rotor is pointing)... Could actually point to any terminal you want it to, as long as that is the one that you run to the #1 cylinder.
