New 440 Source 4.500" Bore RB Block

Yep, depends on what "real" is in the eye of the beholder. I know I'll be pushing the limits of a factory 400 block pretty soon and it isn't "real" to a lot of drag racers.

It sounds as if an 800HP build wouldn't make the new block break a sweat. I'd call that real.
