Where is the casting date on a Mopar Performance Crate 360?
Here are the stamped numbers....
1 N K ? 1991 or 2001?
N K.... I don't see an N defined anywhere but the K could mean Toluca.
5.9L, self explanatory.
1361 = what? Is that the "Julian Calendar thing?
The rest on that line is 1 205A, the bottom line is 469.
Rich and I took the block in to the machinist today....It was standard bore! I thought that ALL of these Mopar Performance engines were at least .020 over. The "1" in the number makes me wonder if this is a 1991 block, the very first of the "Magnum" series engines.
