Aluminum slant block?

Thanks for correcting me with the right info . I guess the engine stamped number list I was using was incorrect or I read it incorrectly.
Can you possibly shoot me in the right direction to learn how to properly decode these motor numbers in the future .
I have a couple part and casting number books. I see these guys are out of stock but someone might have one. Galen Govier compiled the information. Chrysler Corporation Part & Casting Numbers Book 1962-74 Volume 1, Decoding Books, 147-GGB101 Reproduction, NOS and Used Mopar Muscle Car Parts
