With 3.55’s the car will have some nasty top end, but it’s going to be a bit sluggish from really low rolls. I notice a differenced a difference going from the 4.10’s to the 3.73’s, but the longer top end pull makes it worth it. Also, I think the nitrous is going to work well with the longer gearing when I put it back on. I’ve heard of people welding the bolts up, but it’s gonna be a pain when you have to remove them. The safety wire may be the way to go. --- _[View the full topic](https://forums.speedlife.net/t/heads-cam-2002-z28-vs-stock-2009-amg-c63-daytime-vids/257931)._
