VRX5 from Vengeance
I know from talking to Ron at Vengeance that the VRX5 cam paired with the TFS heads on an A4 LS1 goat with a big stall pulled over 450 on their (relatively conservative) dyno. Check out the thread in the dyno results section....I'm pretty sure there's a printout of the dyno pull and it will likely tell you a good bit more about the power band.
