Just my thoughts but no way would I be interested in that sort of a trade. Your 70 K20 four speed and factory a/c will no doubt appreciate in value over the years if kept up. Don't know what sort of condition either truck is in but I doubt very seriously if that 2500HD will appreciate much with normal maintenance. Would depend I guess on what you wanted to drive, a truck many, many people have in the way of a cookie cutter or a truck that will get some looks and comments when you pull into a gas station or where ever. My .02, good luck on your out come.
