Trick Flow 440 heads, The Real Deal?

I guess that some may argue that you can't believe anything the manufacturer tells you because
they have skin in the game but Trick Flow took out a full page ad in the new Mopar Muscle stating
that their dyno mule, a 0.30 over 10.5 to one 440 with a hydraulic cam ( I believe 242 @ 0.50 and
540 lift with 1.5 rockers) makes 620 hp on pump gas with the Trick Flow Powerport 240 heads and
intake.

Furthermore, they stated that a lot more power was available with a bigger cam but they wanted
to show what it could do in a typical streetable combination with what they called a mild camshaft.

I doubt very much that they would want to embellish these numbers on a product that is currently
under such critical scrutiny.
