I made a joking spur of the moment offer of trading my '77 Chevy K20 complete and running plus the 454 out of my Crew Cab for an '81 GMC 1-ton 4x4 with a 350 in it, and an older Warn 8000lb winch. He seemed interested. Now I wonder if I should do it. I'm into the '77 truck about $1000 and I was asking 700 for the 454. The 454 I have is a good running one I pulled out of a motorhome with just under 20,000 miles but alot of years. My '77 has a 350/TH350/203, 14-bolt and Dana 44, and some cab rust. The K30 truck only has 3.73 gears, 14-bolt with GovLoc, Dana 60, 350 motor, rebuilt TH400/205 and an ugly camo paint job but no rust just some dents. The '77. The '81 1-ton. Would you trade or not trade?
