That is likley the casting number of a replacment block, and will be difficult at best to find. Do you need that exact block, or do you just need a 420 block?

I would like that casting number but if I cant not a big deal. Its a 420c with a right hand reverser so its a newer one

90% of 420s were right hand reverses, only the last of 1958 were left hand.
The block number you give was the block you could have bought from parts well into the 70s I would guess.
