Why not just look at the casting date stamped on the side of the engine? -----Original Message----- From: Brian Safford [mailto:hzf9vv@xxxxxxxxx] Sent: Saturday, November 24, 2007 8:33 AM To: 1962to1965mopars@xxxxxxxxxx Subject: 413 block casting / serial number decode help Thanks to Jim Jablonski, I now own a 1962 413 that I plan to 'freshen' and install in my 1962 Dart 440 4-door. I'm perplexed, however, that the block casting number of 1852029, which indicates it to be a 1962 413 block, has 'V 41' stamped on the pad at the left front of the engine. I think the 'V' means it was stamped in 1964. Was it uncommon for 2 years to pass between the casting of the block and the installation in a car? Also, the head casting number is 2406516-2 ... my Mopar book says that would make it a 1964-67 361-383 head. Stay tuned for more questions as I dig into my new project! And thanks in advance for all the great help I'm sure I'll receive from you folks! Brian Safford '62 Dart 440 4-door / poly 318 / max wedge? No virus found in this incoming message.
