Hey all, here's another one...:D

Okay, I've run countless sims on Desktop Dyno. I know it's not accurate but it is very good at showing trends. I'm down to 2 cams which will remain un-named or specified. These 2 cams had the best "under the curve" numbers I could get. One of them was recommended by BR.

My requirements are:

As bad-azz an idle as I can acheive
Power below 6000
Lift that won't make me have to do anything to the pistons or even bother checking (I'm lazy)
I'm on a budget
My 5.0 is a street car. I may run it at the track one time just to see what it will do. It is not a daily driver.
I have a 5 speed with 3.73 gears.

All numbers start at 2000 rpm and increase by 500 rpm for the next number.

Cam "A" power: 118, 155, 199, 247, 285, 316, 337, 341. Average power for cam "A"= 250

Cam "B" power: 126, 164, 206, 252, 285, 310, 320, 316. Average power for cam "B"= 247

Cam "A" torque: 309, 326, 348, 371, 374, 369, 354, 326. Average torque for cam "A"= 347

Cam "B" torque: 330, 344, 361, 377, 374, 362, 336, 302. Average torque for cam "B"= 348

Cam "A" advertises a "lopey" idle.

Cam "B" advertises a "fair" idle.

Given what little I've revealed here which cam would you choose? One cam has higher peak numbers but they are higher up in the RPMs than the other cam. The other cam has a flatter line but not as good a peak number. Both cams would be acceptable.
 
I like cam A because it is making power right up to your shift point of 5500rpm -5800rpm. The averages are so close I doubt you go wrong with either but Personally I think cam B is falling flat on its Face to soon. 5000rpm for a max is a little weak.
