i think changing a cam would be a great idea for everyone. i wanted to know the labor time because a lot of people may not have the experience or time to spend 5 hrs on their daily driver. i can change a cam in an old 350 (been done too many times) but i wouldn't feel comfortable doing a cam swap on my truck regardless of the great power. The reason why i replied was due to the fact that i wanted to see about the cost to hp ratio overall with labor included as opposed to doing simple bolt-on's that mostly anyone can do. After my Nelson tune is broken in around 150 miles or so, i am going to dyno my truck to see what i could get by doing just bolt-on's, that only take maybe a half an hour per and that don't cost much. Yes i should have installed Lt pacesetter's and an ORY but i think that it takes 5 hrs and $450 l8r. I'm just a more bang for the buck type of person, like many other gearheads. Sorry this is so long.
