Thunder Racing TRx v.2 cam/stock heads - 451rwhp/408rwtq! I'll keep this short as I'm tired and need to get up for class in 3 hours. 
I didn't start on the new cam swap until ~10pm as I had to help finish up a C5 clutch install for a customer. I wrapped up installing the new TRx v.2 cam around midnight and put it on the dyno. 451rwhp/408rwtq! This was through the y-pipe and open cutout. The car needs some tuning as the new cam did throw off the A/F ratio some. If we find some time tomorrow afternoon, we will make some more pulls and play with the A/F. We may even swap a LSx intake on just to see what that's worth on this setup.
The new cam lost 0 low end and gained 10hp from ~4500rpm-7000rpms.
I'll post up some graphs, sound clips, and some other info tomorrow after school. I will let everyone know how the cam drives,etc. once I do get some driving time with it.
Time for bed now...
For more info on the TRx v.1 cam I was previously running, here is the thread:

Edit: Added FAST LSx intake/SVO 30lb injectors - 455rwhp/410rwtq; graphs coming later

Needless to say you're upsetting a few h/c customers out there huh? Glad to not have been able to afford heads yet!! Would this cam work with my Scoggin Dickey springs? They say they handle 600 lift. I'm betting you guys are going with crazy duration and lsa's and a few other tricks. If you get a chance, PM me with info.

Come on Jason sell it to me... you know you want to.
redlineZ: you will have to use 921's or a good double spring for this cam. I wouldn't like having a single spring with this cam.
