Not Ranked
I wonder why the block has been O ringed? Flat top pistons, E-brock heads should give compression around 10 to 1 or so, not to much higher than that. Some stock 427's 12 or better to 1 and didn't need O ringing. Hmmmm,,,,,
I would assume it's the real deal, based on the screw in freeze plugs, cross bolts and description. $5-$6,000 is all I would pay. Myself, I'd take it down, double check everything, maybe go with a cam of MY choice, not theirs. Calculate C.R. and do what I had to do to get it at no more than 10 to 1 if it isn't.
