mackave1, I assume that you work at mack I. I used to, now I'm at warren truck. And we are slowing down big time as well. We were off last week and this week. Suppose to get a few more off in August as well. The only rumor I've heard is the redesign of the head to a 3 valve design. Another far fetched one I have heard is that the 4.7 may turn into a 5.1. But I have no good sources on that one. What dept are you in? I was in blocks for most of my time there at mack. Man I miss that place!
