I have a question that I hope maybe some of you can help me with. On a Wedge engine with 572-13 heads a true 15.2-1 CR using the Champion C59CX plug is there any need to index the plugs? I have been told it is a waste of time,but I will do it if it helps. In the past I have never seen in results one way or the other at the track. Also what number Autolite plug would I need to use? I run alcohol if that matters. Indy says use Champion but I will try a set of Autolites.

PS Great post, I am always eager to learn more Speed Secrets!!!!
