413 stampings?

Can someone decipher this? It's supposed to be a 413. Has a block casting number of 2205697 and a casting date of July 26 1963. Top pad reads as such:

VC3
18 94C

V means 1964 but should there not be a "41" after the V?

Could be a level 3 industrial block? Chrysler used 1-3 on their truck/industrial motors to show light duty -1, medium duty -2, and HD -3.

Just throwing out an idea for you.

Just checked your casting number and it does not show as a truck/industrial block number. It also shows that that casting number was good through 1963 and changed for 1964. Maybe just a late '63 block that was a replacement block?

A Chrysler New Yorker body is called a PC-3 in the factory literature. Maybe that is where the C3 comes from.

Thx for the reply, the PC-3 thing sounds like it could be it. I think I read that the 300K's had "300K" stamped into the pad. A friend is looking at buying this motor and the stampings had me abit perplexed.
