First time on dyno

Had my barracuda on dyno for a first time today. It did 452hp 467torque at 6000 is that good, Street machine for cruises and shows. That was the best of three, the other 2 runs for very close.

That would be "RWHP" rear wheel horse power? If so that is very good, it's like 20-30% HP loss for the drive train.
