440Source has exactly zero blocks to sell. Making a "sorta" accusation without checking the facts is just ignorant.

If you want to see what the differences are between older and later blocks this will help:

It has pictures, so everyone should be able to understand.

Of all the things in the world to save, original 440 pistons would be close to the last, and I've been called a hoarder by my wife. If you were selling the aluminum it'd be a different story because they are just flat heavy. Like two pounds per piston heavy.

There were millions of B engines produced. There were about 750,000 440s produced. There isn't a big pipeline with new 440 blocks tumbling out of the end. So if you are in a location in which you can pick and choose blocks in the $100 - $200 range, consider yourself lucky. What I am seeing is 413 MH engines for $750. 440 blocks if they are in good shape are advertised for $500.

Anyway, Bah! Humbug!
