That's because the block is the weakest point, but the stock rods and crank are not far behind. Being mass produced and originally designed to hold 225 HP or so, I wouldn't put much faith in them past what the block is capable of holding.
I suppose if you really wanted to know bad enough you could assemble them into an aftermarket block and find out?
