    We'll be doing a right up on a cam install very soon.
    The exhaust after the headers was stock except a flowmaster, no cats.
    The cam install time depends on the installer, but 4-5hours is typical.

    sounds good..

    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.

    Allen,
    How did you get that truck to hold the HP all the way up to 6500? I put down almost the same peak HP with 30 extra tourque but it drops major after 5800.. any ideas?

    Max power was actually about 6200rpms, but we revved the engine to 6500rpms to see the full graph.
    What kind of valve springs are you using?

    here is my run it sounds good all the way to 6400 but the graph just drops around 5800.. You probably know me better By Bryan since you have done so many retunes for me (Thanks)

    I know I have to setup my rev/? on my dyno to record the correct RPM, maybe the dyno ignition or sensor isn't calibrated. If I don't set mine up, actual rpm and dyno recorded rpm are about 600rpms off.
