I reciently completed a Dart Pro 225cc heads and custom Comp Cams cam install on my 01' SS. The results are  411 RWHP and 396 RWTQ. This is with a small 220/224 cam, Dart ported/polished and ceramic coated heads, Kooks LTs (with catted y-pipe). The average under the curve is excellent especially the torque at low engine rpms. I have yet to really reach the full potential of this H/C combo as it is still running on the stock fuel pump and injectors. I'd say there is another 20-30 RWHP available with high flow injectors and a Walbro 225 gpm in tank fuel pump (and a retune). Here is my dyno sheet;

Very nice gains!!! Isn't that a big head(225) for a small cam? I guess you are giving your lsx all the breathing it needs and more.

Those are some great numbers for that cam size!
