Make your car #'s matching!

I seem to remember that you could order a replacement block from Dodge/Plymouth. When doing so, you could tell them your VIN and they would stamp the block to match. Some just left blank like this 340. My dad's 440 Magnum in his '70 Charger R/T was a replacement block with the VIN stamped by Dodge.

So really it's not totally incorrect.... :p
