Looking for X-ER lobe designs Does Comp offer any more lobe designs run on X-ER profiles other than #3720-3734?
Interested in smaller x-er profiles. Below 220 duration @ .050 where the 3720 starts.
I guess I should probably ask, can Comp grind you anything you want? Or how do things work...

Here's a link to our website page that lists all of the cams we carry, including 3 of the Comp X-ER grinds.

If you do want to get a custom grind made, just let me know, and I'll help you take care of it.

I'm confident in what I want. I was curious mainly because I've been looking at an X-E Comp lobe , but I wanted to back down the exhaust lift just a tad.
Thanks for you guy's help.

You mean less lift? if so you can't use XE-R since they require higher lifts. I've never seen an XE-R with less than .57x lifts.You could get a cam with mixed int/exh ramp rates. ie: XE-R /int and XE/ exh.

I am starting to decide how to build up my ride now that I have a different daily driver. Life insurance prevents me from running at the track, so my primary want is for great torque for a vert good SOTP feeling on the street (I do NOT street race).
Anyway, would something like a 216/216 112LSA with an XER lobe achieve my goal?

Ed, what would be the specs for such a cam that you would recommend/custom grind for a setup that has the usual bolt-ons including stage I heads, LS6 intake, long tube headers with cats, a pulley, ported TB, and a lid?
P.S. I guess you're saying that an XER lobe won't work within the framework of a 216/216 112 profile?????

Small duration for keeping stock power band. Would you probably soften the lobe up, to keep valvetrain ware down? Or would you not consider the x-er line that extreme?
I've had on my mind a 220x-er/218x-e for some track use, mainly street. Tighten it to a 109.
stock heads,
bolt ons
Got any ideas on how to squeeze more power out of it

FWIW from 216* thoruh 219* are available... Up to .600" lift also... Nothing over 5800 rpm though... That's as far as the free info goes...

You want torque, run small duration cams on tight lsa's. They will have a peakier power band but will own in the stock rpm range.
My first cam was a 224/224 106icl 110lsa 568/568 comp xe cam. This cam made 380 rwtq at 2800 rpm and peaked at 406rwtq at 4800. Rwhp was 405 at 5900.
This was on a stock headed full bolt on 01 SS.
Try something in the 220 range on a 110 or so.
What is the dimensions of the 5.3 (bore and stroke?)?. This will impact the above recommendation.

DAPSUPRSLO, thanks for the suggestion. I hsould have added in my previous post that I live in an EPA county - I have to pass emissions. Would the 220/220 110 XE lobe still be OK given the sniffer test?
Tis hard to say. In a 346 I don't see why it wouldn't as you would have less overlap then a 224 on a 112 and the same as a 224 on a 114 which everyone seems to pass with. I am not as familiar with emissions as my previous cam, after the one I mentioned in the above post, was a 230/236 on a 107lsa and my new cam is way larger and has a tighter lsa. In other words, I don't have to pass the sniffer.

Did you ever design "off the shelf" grinds after all?
You mentioned designing a couple of grinds to sell "off the shelf" awhile back.
Hope nobody gets their panties up in a wad about this one

I have some "areas" I'm working on but there are still some subtle differences people have in their vehicles that mess up the "box" cam ideas. What I'll probably do is come up with a few ideas for each of the four series of cams I have, note the required peripherals and see how well it is received. The end result is the "end user" will pick out the cam design that fits their combination and purchase it. I think working with a few cylinder head shops and installers is also a good option. I do it for the Ford shops so this also may be a benefit for the "impulse" buyer.
Now...
For a high torque camshaft, I like DAPSUPRSLO's thought process but you can still make great torque with a "relatively" wide LSA, so a narrow LSA is not a mandate. As I always say, it's all in the combination...
What I'd like to see a typical package is small port volumes and a very efficient intake port, long runner manifold and some small diameter long tube headers. Those parts coupled with a high lift, short duration camshaft, somewhat high compression and a good tuner will rip the U-joints out of a car/truck with some traction. I've done this in the past for the snow plow trucks up here in the northeast and no one has had any trouble pushing some serious frozen water...

Would something around 212-216 inlet duration ground on 111LSA be too tight and cause power to roll off too early? Ideally, I would like power to peak around 5800 and slowly roll off from there to 6400.

If it was on the same intake centerline (icl) as my previous cam then it would roll off to early I think. Now, if you back it up to a 110 or 112 icl I don't think it would roll off to early. You will give up some peak power though.
