Early 340 identification and value

I would not sell that engine as it sits for less then $1500.00 The $500.00 price quote is not even close. Of course most people dont see the value in these old 340 with all the crate motors avaliable nowadays. You will proablly need to find someone putting a 68 car together that wants a correct motor. Me on the other hand a guy that grew up driving these 340 cars back in the day would not trade on of them for anything, they were some of the baddest cars around on the street in the early 70's through the early 80's.
