Silent cam modification
Mine is not "perfectly smooth" but very close and no one has ever known I have a cam. More HP than the LS6. A custom grind w/LSA 116 should do the trick and give you more power than a stock LS6 cam. I almost went LS6 but I'm glad I went with custom instead an LS6 cam. Pulls strong yet near stock idle.

If you are required to be *stock* then LS6 cam and ported/milled LS6 heads (with hollow valves) would fit the definition of *stock*... you might look into low lash solid roller lifters to extend your rpm.
Your tune would run peak power slightly leaner than peak torque, and it would run slightly more timing throughout with a thermostat.
Also, what can you remove from car to lose weight (donut spare, jack, rear seat back)...?

4cam motors have much more accurate valve control due to lack of pushrods which allows power to be made much more freely.
Never said the gen 3 couldn't fair, it just can't fair easily with the OP's request.
Let them figure out cam timing, and that nose will turn into a set of tail lamps.
4 cam motors just love high rpm's while continuing to make power. It's an uphill battle for a pushrod v8.
I would contact a vendor and ask them for some help. Remember when trying to achieve high rpm power from a pushrod motor; valve control is key. "Key to extra secret power"

I know it's been beaten to death because I have searched the forums through and through. I still haven't really found what I'm looking for. I race a local race that my LS1 has to stay stock internally. I'm allowed a full exhaust and cold air intake as far as the motor is concerned. Is there anybody out there making a cam that will increase power with a Absolute stock sound? I don't really care as far huge Dyno numbers. I need a little edge. I'm going to do some head work as well because it is undetectable and a tune as well. Car is a 2002 WS6 if anybody is curious. I know I'm cheating before anybody decides to bust my *****, but there is some 2015 coyotes with a full exhaust and some secret tunes and they are barely edging me out. Can a brotha get some help? Any info will be greatly appreciated.
FWIW I'm getting ready to take this cam out and go bigger if you're interested. The cam has less than 200 street miles and probably 20 1/4 mile passes. I'll make you a great deal on the cam and PAC springs if you're interested.

Limited travel lifters are great. I run them. Johnson 2126ST's
But don't misunderstand, I thought your idea was a great one. Just have to remember that the presence of valve lash means you would have to run more duration to get the same "duration" as you would with a hydraulic set up. So, you'd order a cam that was basically LS6 durations + 8 degrees, and then you'd need the adjustable rockers - or do what Thunderstruck is doing in his thread.
For the ease of installation, I would go with short travels and a stock-ish cam, but if I had the time and money to throw at this type of racing, then I would go LLSR and follow Thunderstruck's thread
