Spark Plug Gap

[Nate882004]

So, I’m replacing my ignition coil, cables, and spark plugs. Wondering what you guys think the gap should be on the plugs.

Using CarQuest ignition coil and premium cables with Autolite copper plugs. These plugs came with 0.04” gap.

Update: Sorry I forgot to initially put in very important details. I have a 96 with 5.8L v8. Also, if you work at the parts store, its a 4x4. LoL!

Yo Nate,
Here is a popular Sixlitre Tune-Up Info (scroll through pages to view more tips, especially on Page 5); "...Yes, stock timing is 10 degrees, I find optimum timing to be almost exactly 13.5 but you can play around until you notice ping and then back off 2 degrees if you want to, and/or tune by vacuum if you care to. Cheapest Autolites money can buy, nuthin' platinum, nuthin' fancy, just set out to .055 gap..."
