Bruce, the point of the video was to show how normal the car sounds. If you are happy with how smooth your machine runs then the cams are of no consequence to you. I installed the cams just to see how much of a difference they made in smooth application of power and overall driveability; they helped IMO.
Since I installed them I have the skill to remove them if I think they are not worth it. So far they are staying, along with the roller rockers.
The biggest drawback to them that I have noticed, besides a decrease in fuel mileage, is the ease at which high rpm's are reached. It revs very freely and forces me to pay closer attention to the tach since my ears have not gotten full adjusted to the engine sound yet. With the stock cams you could tell the engine did not want to exceed a certain rpm freely and you had to push it to go higher, now a rev limiter set might be a good thing.
No, not a grunge, just someone who is enthusiastic about his MOG and what it does :-)
