I built a 511"(stock block) Mopar late last year and had everything needed within a couple weeks after a few phone calls.
I'll go out on a limb here and say that had an aftermarket block of similar strength and quality to the Brodix BBC iron block been readily available for around $2500($500 more than they cost for the Chevy).......you'd have bought one for that build.
