Not Ranked
I would lean towards that 427R being hurt then.
I've built/dyno'd a few 427FE's with factory parts and they wouldn't touch what a Roush 427R should make by a long shot. A Roush 427R should be in the 525-550 hp range. You're saying that your FE with all factory parts made almost 600 hp?
Not saying you're wrong on what you saw, but logically, that should not be correct.
