Stock Idle cam
I want good cam with good midrange to top end power something that its power band is from 2800-6000 rpm
I will have a 3600 stall but im not gonna stall it always because Its a 4l60e.
But I want a stock Idle cam even if a little more but not the 114Lsa so Help me make my custom Cam and who do you recommend for taking the cam from.
Another question What is the difference between the XFI and the XER lobes and does it mater if I have both in the cam ?

You can mix and match lobes from different families with no problem. You're going to need a wide lobe center to keep the stock idle quality. A 114ēlsa or wider. Is your engine a 5.3L or 6.0L?

Call up Comp Cams and have them grind you a 206/212 .515/.522 on a 116LSA. It will be a custom grind, since the closest camshaft is the 206/212 .515/.522 on a 112LSA. That particular camshaft will give you an RPM band closely mimicking that of a stock LS1, 850-6150rpms, in a 5.3L V8. You will feel an increase in power across the entire range of the tachometer, and after your tune, probably see an increase in mileage. Could one ask for more? Of course, this is assuming a 5.3L, which is safe to say considering GM makes the 5.3L V8 in a ratio of 3:1 compared to ALL other LSx based motors in production. The 5.3L is GM's bread and butter motor.
I would leave your stock converter in your tranny just the way it is. This cam will still work perfectly with the stock converter. If you are dead set on changing to a slightly higher stall speed, try the OEM Trailblazer converter. It's stall speed is 3-400 rpm's higher than that of the stock truck converter because the Trailblazer weighs 4300-4400lbs compared to most ECSB trucks weighing in around 4600-4800lbs.
The difference between the lobes is that one set is more aggressive, the XER lobes being the more aggressive style. They bump up cylinder pressure and make more torque across the entire rev range, at the cost of short valvetrain life. I would personally change springs on an XER cam that is rather aggressive (anything over .560" lift for example) every 40-50k miles.

Mine is a 5.3L. Can I take a 216/220 .515/.522 on a 116 LSA and Whats the rpm rnge for that I'm going with a 3000 stall converter because I need it in the future and I have toomany trans parts sitting at home so im gonna rebuild the tranny one time .
While making a custom cam it says choose the ICL What is this ICL and what do I chose?

A 216/220 .515/.522 on a 116 LSA is getting a little wild but with a really good tune I think you can tame that beast down to keep your low end power where it belongs. I've been bombing around in two 6.0L trucks lately, both have 218/224 cams and are set up to be powerful daily driver trucks. Ask hirdlej about his 6.0L swap he just finished, he's actually looking for a lesser cam because a 218/224 isn't ideal for him as a daily driver. You have a 5.3L, which means the fewer cubic inches will make the same 218/224 cam feel even more wild. I would not go any crazier than the 212/220. I think with a stock or slightly mild Trailblazer converter you will really like the build you have going.

do some more reading, i have been seeing people given some shitty *** suggestions, and that is people are new to the site, havent even been here 1yr and they think they have all the solutions....
but if you want my opinion, my friend had a ccsb 5.3, with a 220/220 .581/.581 115lsa, truck sounded completely stock, and ran a 13.5 in a crewcab, that was with a 3k converter.... rule of thumb, always go the next level bigger cause you'll want to change it if yo dont...

My 206/212 114 sounds stock and is a noticeable improvement over the stock cam across the entire powerband. I'm also running a stock converter. IMO, any bigger than my cam in a 5.3 and you'll want a higher stalled torque converter to optimize performance, although many have run larger cams with the factory verter and still have nice gains.

I follow the rule of thumb when picking a camshaft, find one I like and step down to the next cam smaller. For example I was dead set on the XR265 from CompCams (212/218 .522/.529 on a 114 lsa) and went to the XR259 instead in my signature.
That's just what I do, you all keep doin what you do. We all have different ideas of what our ideal camshaft is. Cams are kind of like ice cream...there's a bunch of different flavors and ya just gotta find the one you like best.
