Found: 68 GTS Engine

Thanks to the great community here I was able to identify the 340 sitting in my Coronet. It belongs to a 68 GTS. Reach out if its yours!

Date stamp: 6/22/67, N (night shift?)
Casting Stamp: 2780930-340
EIN or VIN: 8B392511
Serial Number: DW34022450139
Can you send me a picture of the VIN number off of the block. What history do you know of where it may have come from? The production date is very close for my missing 340 gts convertible. I bought the car 30 some years ago, without the engine and am looking for clues . Prodution date of my car is AUG. 11 1967.
