340 block Vin #

That has nothing to do with an assembly plant. The "B" is the assembly plant. LM23P is the VIN for a true 1969 x 340 Swinger. The L is on the block as well.. just so light you don't see it in that shot. They were still on full VIN's I guess when my Swinger was built. My '69 Bee only has a partial... a 69 Roadrunner A833 I have as a spare has full VIN. Depended on car line and timing as to when they started getting lazy.

Yea B Is Hamtramck Mi. On the front of Block It Has J for 73 witch mine is M for Mound road 340 but 0 is like half but No P that can be seen the about 2 inch gap and the 4122 for 10,000 date but that is 63 days before my build date 1/17/73 10,000 is 4191 then 9198 for unit day count.. But Damn 9198 is a lot of motors in a day
