[QUOTE="JDV, post: 10834708, member: 11965"] It was not. It was the cylinder with the least amount of flow around it (coolant supplied to front and pulled out of front). But, chevy and ford been like that for years. No returns to the front from the rear coolant crossover. That's nothing new in the horrid world only something that is brought to light when you push for every last bit. The old days of reading plugs (or checking egt) is gone many are trying to tune without fully understanding the engineering behind the mechanical equipment. Plugs would show that those cylinders where getting hotter first and the limit was being reach. The downside of wideband tuning is that you only see the average outcome of all cylinders. Could very well be lower coolant flow on the #8, I havnt looked at the coolant flows in these, but I still stand behind what I say. I it's not popping stock ones, then it's not fords issue, it's a tuning issue. Every mechanical thing has a weak link, a part that will fail first when operated outside of it's deigned parameters. It can be tuned around once found, but as long as they are Living when stock, ford did what they are obligated to do. I'm still wanting to see the supposed stock cars pistons to see if it is showing the same symptoms as the tuned ones. [/QUOTE]
