i just saw this on FB, not mine, 'friend of the forum', no personal experience with him but he seems like a straight up guy. never heard any complaints regarding him before etc.
it's a DOAE-L casting, the early blocks were better than the later D2 series even being 2 bolt main. they were built to higher output standards with potentially thicker cylinder walls.
are you interested in a ready to start assembling block? that way you can spec your own components and be sure of what you have when completed.
