Spark Plug Reccomendation
I've got a 462" with #62 heads on it. 12/1 compression. Cam is .516/.534 244/248@.050. I have Autolite # 85 plugs in it now, but they seem to hot for the combo. The heat marks on the ground strap are real low near the threads on the plug.
What plug would you recommend? |

Plugs have about a 1000 degree temperature spread where they wil not over heat or run too cold and foul out.
The bottom of the heat range is like 500 degrees so what you need to do is to just drop down one heat range in a Autolite plug and you should then have the color change over point right in the middle.
