You are planning to step up the system and use a hotter plug at the same time? The shops may be out of plugs but when you are done they wont be out of pistons and rings in your size............. Call Summit or Jegs I'm sure they have plenty in stock and can ship them overnight................. Just sayingRight now i run a -11 NGK plug and everything is fine, what would happen or what adjustments will need to be done if i go to a -10 plug??? right now i run a 36/28 jet spread in a fogger. Possible stepping it up to a 42/32 jet spread next weekend. Im asking because since its the end of the year where i live most shops r out of the 11 plugs and not ordering anymore till spring so my only choise are 10's
This is what I was thinking along the lines of as well. If you go to the -10 of your CURRENT tune and pull a couple of degrees, it should be a safe move to see just where your at. Address tune based on the first pass.. SJ
Advanced is always able to get them by the next day, and they're cheaper than most places. I prefer NGK too, but if push comes to shove an Autolite AR3931 is the equivalent. I noticed Billy Glidden using them a few years ago, so I figured I'd give them a try if I couldn't find NGK's.
If you're asking me about my post, yes. I don't know about the OP.
sounds good Steve I will give it a try, i also run a MSD grid system so i can ramp timing in and out of of my current tune up. Im up here in Detroit and its like 50 degrees outside tuning is a PITA, Im heading to Mike Hills race at HOH in South Caolina next weekend were the weather will be warmer so tuning should be a little bit more easy to do.
