Stealth,sleeper cam
Keep in mind he's going through a 4l60 and a less efficient rear end too. Those heads flow 80% , I'd probably split it a little bit. Run as big of an LXL lobe that you feel you can tune to keep quiet at idle. Or your tuner. With those heads you could probably hit 360 with a stock cam. I like that 223/226 blu posted on thise heads. When you said cnc'd 5.3's I assumed the worse
If he was wanting to be a total sleeper and to have a little more top end wouldn't it be better for him to go with a 118 lsa to reduce overlap and raise powerband slightly on the cam you were using?

Wouldn't the gas mileage, idle, and drivability outweigh the slight loss in efficiency though and wouldn't with a high stall 4000 - 4500 auto the 2 lsa wider difference likely would not be felt at the track? A question to ask the original poster when considering shift point on a 4l60e though would be to make sure he has done the necessary modifications to the transmission pump, valve body, shift kit, and pwm eliminator to safely rev the 4l60 in the 6800-7000 range and not lose fluid pressure and to daily drive the car with the high stall and not chew up the torque converter clutch.
With those great heads I'd be tempted to run a LxL lobe and 1.8 ratio rockers. Do keep in mind OP that the higher the lift the more wear on your guides and rockers. Try to keep it near .600 if using all stock stuff. Upgrade the to the trunion bearings while your in there. Im gonna start playing around with numbers later tonight but I think I'll end up trying a 230/236 on 115. With my cutout closed through the stock muffler at 800rpm, Im positive it'll sound stock. My 232/243 on 114 was tough to hear lope through that 50lb muffler

The smallest LXL lobe of 214* is .630" lift with a 1.8 rocker, personally think that cam having a 3* overlap will be noticeable. Depending on the advance that cam will peak at ~6500 and I like to shift atleast 500rpm past peak to take advantage of the full powerband.
My main goal is to have as much torque and more power than the Z06 cam, stealth, 30+mpg hwy, and had hoped to use a low lift lobe. LsL's were the smallest that would outshine the GM stick all over. Im trying to replace my civic with the camaro as a 2-3 day a week car. Driving 50hp every day is miserable.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo IIRC that one only made 10-20 up top, and lost some down low, plus it still needs better springs. I tried that one and similar ones, thinking I could just shim the Z06 springs I have. But the one I came up with made 5 more ft/lbs and 5 more hp across the sweep, 25 more at 5800, 42 more at 6200, and 35 more at 6500. My other goal is for the car to run 11's with a 3.42 gear. Sorry for the Hijack OP, but we do have a lot of useful discussion going on.
My old cam was actually a 236/242 XER on 114+3. It was only noticeable with the cutout open, it was in an LQ9 though so that helped a little. I finally got a cam to make more torque and hp than the 04 Z06 cam...took some work, but I'll be ordering it next week. It would definitely pass the OP's stealthy sound requirement, but only makes 35hp more at 6500. Didn't TSP sell .650 lift singles in the past? I couldnt find them on the site.

I'm not a fan of maxing out the lift. I know it will work with those springs, just at the limit. I did confirm that GT2-3 is making 13 more hp at 6500 and 7 more at 6k versus the 02 Z06 cam. The Z06 cam is making 4 more hp and and 5 more ft/lb until crossover. Mine is making 8 more hp at 5500, 20 at 6k, 37 at 6500, and 53 at 7k. Only down 6ft/lbs at 3500 and 2000, two little dips in the graph, all other spots it is even or above. What speed were you going on that trip? What gear was in it?

With all due respect but; WTF??
You do not want lift, you do not want durations (stealth), no compression increase so what is left to make power, hein?
What do you think, there is a Magic stick out there?
Come on be realistic!

Although I've been tempted to try a few of Martin's(TICK) cams I'm still quite
impressed with my EPS 218/226/.595/.598/117+3. I think Geoff sells it as a
truck cam and with long tubes and .030 milled 241s I consistently get 30+
mpgs and the idle is completely smooth at 800.

cats to LTs w/3" hi flos but it did gain a solid 2.25 mph(117.6 to 119.85) in
the quarter. At Speed Inc. it peaked at 365/344 but it put over 300 tq from
2600-6300 rpms and I shift it at 6700-6800 (wide LS and hollow ls6 valves)
I can only speculate that it's now closer to 380/360.
Sorry for the confusion pred, I'm going with the LsL lobes. I wanted to try and stay with the low lift, it just wouldn't make the power. I went 217/221 on 112, stupid phone must've not posted that one. Of course now that I've ordered it there's suddenly a ton of interest in my part out of that car...figures.
Jenson, what's the ICL for you new cam ?
BTW, did you ever look at the Lunati VooDoo #20540713 ?
