I have two questions. Where can I find a Picture diagram of the correct placement for the spark plug wires on a 1990 Chevy Suburban 5.7L V8 and what is the proper gap for the plugs?
Gap is .045
Firing order is 1-8-4-3-6-5-7-2
1-3-5-7 is on the driver's side
2-4-6-8 is on the passengers side
I suggest you get either a Chilton's Repair manual, or a Haines Manual, but I doubt they'll show the exact wire setup, if you look at your Distributor Cap, you should be able to see the Number "1", from that, you'll need to know the rotation of the Rotor, and the firing order, which you can find in your repair manual, Make sure you install the longest wires, on the furthest Spark Plug(s), from the Cap, and with those in mind, that will give you what you need...Good Luck
I would go to your local auto parts store and purchase a manual for te vehicleif you own it. I get a manual for every vehicle I own and it gives you almost everything you need to work on your vehicle. If you don't plan on working on it then I would suggest getting a good mechanic.

That was soooo helpful. Why didn't I think of that? Perhaps because in this economy I am BROKE.
