what year did they stop making 340 motors??

I have been kinda looking for 340 motors online and found one recently for $300. Im on a budget right now and have been trying to find something that wasnt a crazy amount and within a reasonable drive. This guy happens to have it says its a 1986 block, i know it has an edelbrock intake and a holley carb. Can that be right to be a 1986??? I have never seen anything that new for a 340 any info would be appreciated thanks
