Best ls3 cam for midrange power I'm looking for recommendations on cam specs that will maximize power under the curve, specifically in the vicinity of 4000-5500 RPM. The engine is a LS3 motor with stock internals, a ported ls3 manifold, short ram intake, either factory headers with a single high flow cat per bank or 1 3/4 inch long tubes feeding a 3 inch straight exhaust.
The car is used for road course racing so I find myself in that RPM range a lot. I'm less concerned with peak horsepower gains. Let me know what you think! thanks!

I personally like my 231/243 .617/.624 113+2 in my ls3 5th gen makes LOADS of midrange torque.
Alot of other people who do roar racing seem to like the Katech LS3 Torquer cam since it was designed by katech specifically for that purpose.

I'm a surprised you're interested in such a small power band for road racing. I've been looking for similar cams for awhile but have been looking for 3000-6000'ish. For off the shelf cams, I'm partial to these for a wide power band, in this order:
Lingenfelter GT11
Crane Cams 2019381
Tick TorqueMax Stg2
Katech Torquer 3

LG Motorsports has their G6 series cams also. Or, you could contact Ed Curtis, Kip @ CamMotion, Martin @ Tick, Patrick Guerra, etc, to ask about a custom cam

If you are willing to send me the following I can make recommendation:
1. max shift RPM
2. trans gear ratios to define RPM drop on gear changes
3. total intake track length with you custom manifold
PM me if you're interested.
Thanks,
Aaron
