Early 340 identification and value

Thank. I'll get the VIN# off the block. I had a tough time deciphering the casting
numbers on the intake runners. I'll pull the heads and get the numbers
underneath. I would love to reunite it with it's car.

You don't need to pull the head. Just look for a letter next to the spark plug hole. If you don't see a letter just take the valve cover off, the casting numbers are there.
