Before the core price went through the roof on these engines, I used to buy them, take out the crank and rods and keep the main caps and send the rest with the scrap guy.
The 427 truck block is an excellent basis for a cheap stroker engine. If the block sonic tests ok, you can bore it .100 and put a 4.5" stroke crank in it for a 535 cu. in. torque monster.
