I have always been of the opinion that a 427W is over stressed the minute it's put together. Oh sure it is common number, just not one I would ever personally go for. Just to much bore and stroke in that tiny block for my liking. I'd take it to maybe 402-408, MAX, if that far.

...but maybe I'm just being paranoid, don't think so though based on the reports of so many problems with a number of 427W's built by anyone, not just Roush. Most recent example I personally know of was a blown head gasket, (Roush 427W motor, by the way).
