With my cam and the original 99 PCM it was a dog because of KR issues (99-00 PCM's are junk). With an 02 PCM, it will idle straight up without any tuning, and run decent. With a tuned 02 PCM, it's great...very torquey and fun to drive, especially if it's your daily driver. I see that your truck is an 04, so you won't have any of those PCM issues.
With my PCMforLess tune, we have the idle set at 650 or 675 (can't remember exactly), and it pretty much sounds stock, with 17 in hg of vacuum. Right now, Bryan (PCMforLess) has my PCM and he's updating it for e-fans, so I'm using my back-up 02 PCM and my VHP tuner, set to cam1 tune, idle in gear at 625, and I'm seeing between 16-17 in hg of vacuum at idle.
I'm looking forward to seeing how it's going to respond to the e-fans, 160* stat and Yank TT2600.

That cam is great, I had it in my 4.8 & had NO IDLE ISSUES once it was tuned properly, it almost sounded stock with my idle set at 750, I ended up dropping it to 500 just to make it lope.

Mr. Sandog

You PM'd me, but I thought I would respond here just in case other guys have opinions or input.

With a 2600 stall (I don't know which one you're talking about - the Trailblazer stall, which can stall anywhere between 2200 and 3200, depending on weight and horsepower - or the TT2600 from Yank) you have a little more flexibility if you're willing to go up the powerband a little. I told Cam Motion that I was sticking with the stock converter, and that's how I ended up with the 205/212. Any higher with a 5.3L and you begin to creep up the powerband - your power starts higher and higher. Since I told them I was keeping the stock converter, the cam I got was their recommendation.

For example, you could get a 208/214 from Comp - they can make that grind for you on a high lift - and your power might start at 750-800 rpm instead of 650, like the 206/212 would. Or you could get a 210/216, which again, Comp could custom grind for you, and then your powerband might start at around 900-1000 rpm. This is not a problem if you're willing to go with an aftermarket converter, and also if you are willing to wait a few hundred rpm for your powerband to start. Do you follow what is happening here?

The payoff is you will get incrementally more power with a cam that has larger duration (for example, I got 15-20 rpm all over the powerband, whereas you might see 20-25 with a 210/216, or even more with a 212/218) that peaks a little higher. The cost is that power moves up the RPM scale the more duration you have. If you're willing to use your right foot and the higher stall converter to jump you into the powerband a few RPM's up the scale, then perhaps a 208/214, 210/216, or even the 212/218 might work for you.

At minimum, I would fill out Cam Motion's cam request form in detail and see what they recommend with your specs. Before you do that, I would get clear on what converter you are getting (trailblazer converter, Yank TT2600) and find out by asking guys here what theirs is stalling at with their weight and horsepower, using that as a reference. The more weight, the higher RPM it will stall. Same with horsepower, the more HP you have, the higher the stall speed. Then put this in the comments of Cam Motion's request form (something like "TT2600, expecting to flash stall at 2800 RPMs").

Good luck.

What would be the best deal a person can get on a cam motion grind?

thanks for the info everyone..

AV: I get whatcha saying. I think some said the TB2600's were stalling to like 2600-2800 on the ECSB trucks.

Any idea what the cam motion cams run price wise? Ill fill out there form later, but just wanted a rough idle how much some of their cams run in price

Thanks everyone

Mr. Sandog

$385-$395 or thereabouts.
