Hey, nothing to be sorry about. My last commment was directed elsewhere...You're right on track with what I was looking for I just have to get further into what can be done with the coil packs now that we've identified that as a possible problem. I know of a few guys turning 7400 without the slightest ignition issue. I wouldn't think another 600rpm would be a problem. But, I'm no electrical engineer...
