OEM 383 using a 361 Block ?

I have one. - The casting number on the block indicates 361, and the stamped info, on the pad, near the base of the distributor indicates 383. -- I talked to a Guy that worked in a Plymouth Dealership, back then, and He said that the stamped info actually indicates the cubic inches. - I've been told that this sort of thing was done by all of the Manufacturers, back then, due to running short on various parts. --- BTW -- I just checked this since My original post.
