340 ID help

340s were used in A, B & E bodies for the 1971 model year.

No B bodies were produced at Hamtramck at the time, so it is from an A or E body.

Can you tell from the VIN what car it was? How does that second number break down, if at all? Or is it simply a number that was assigned to that chassis?

I'm not a real numbers matching kind of guy but it would be satisfying to see it find it's way home. The original motor and trans from my car were pulled and set aside and then sold off and built. I doubt I'd ever be able to afford getting them back, and that's OK for how I plan to do the car.
