Although typically the GM LS-motors take pretty damn well to making big power. Either way though, I'm sure it's probably a hoot to drive!

It was a Mustang. He pointed out that on the same dyno, his SS baseline dyno was 319 RWHP. So it's pretty good. He also pointed out the Vette ZR1 puts down around 525 RWHP on the same dyno.
Here is a summary of his mods:
# Magnacharger Supercharger
# 3.600 pulley
# Borla Long Tube Headers
# Borla Exhaust
# LS9 camshaft – 211/230 – .562”/.568” – LSA 122.5
And a custom tune by the company that dynoed it.
