Motor is somewhat similar to the one in my car, and it puts 450/408 to the wheels through a 9".

Fist off what other mods? A4 or m6? 97 your heads and compression are much more than his. I'm guessing with LT's and an m6 400 rwhp A4 depends on converter maybe 360. Do some ported 5.3's and you should pick up another 25 or so.
Good luck with your combo sounds like a fun street car.

Only 400 horse with a ported stock headed T-rex car??? I would think he should make that cam only even at stock compression.

Yes the cam hits very hard. You get it up into the power band and its like someone flipping a switch. Haven't had it to the track yet, have some issues that I have to work out.
