Firing order

[Skoobie]

Is this the wire for the #1 cylinder?

If it goes to the front most cylinder on the passenger side of the car, then yes it is. The wires dont have to be in any specific position for the car to run, only have the right orientation to the rotor under the cap.

Some will argue that the car runs better with the number 1 wire in a certain position on the cap.

Skoobie - on my MSD cap, there is a number "1" on the cap to orient things from the outside. But, the #1 wire is the wire that goes to the number one plug. As hllon4 says, doesn't really matter where it is on the cap as long as 1) timing is set accordingly, and 2) the firing order is correct. As a practical matter, there is a limit as to where you can put the #1 plug, and still rotate the dist. enough to get timing correct without having the wiring harness bump into the t'stat housing on one side, and the a/c brackets on the other.

if you have a repair manual, the firing order (HO, not non HO) order should be in the first chapter.

if not, and this is still unclear or you just want the firing order, someone keeps posting a very nice diagram of the firing order.

good luck.

5.0 firing order should be as follows, according to Chilton:
1-3-7-2-6-5-4-8

(that's in a counter-clockwise rotation on the distributor)

But id be careful if my memory serves me that firing order is for the no HO, the HO starts with 1 5 7 I think......might wnana check it out.

HO & 351 use a different firing order from the non HO engines.
HO & 351W 1-3-7-2-6-5-4-8
Non HO 1-5-4-2-6-3-7-8

Joe's right 88GT - your memory isn't serving you. 137 is HO/351W, 154 is nonHO and Cleveland....
