NOS 6 Pack, 440 Crate Motor?

[incinr8]

From From another site I visit. This Gentleman, Apparently has a Crate motor, presumabably from Mopar with no vin on it. Never been fired. I'm trying to get more info on it but it seems so far that the only numbers stamped on it are by the Dizzy "G440HP WT" Anyone have any info on these, Ever heard of such a thing?

I think you'll find what you're after on that stamping here, 3rd post down:

Basically, those numbers translate to a 1971 HP build that's been water tested originally, if I'm reading things right?
