I am thinking of buying a late 80's model crew cab K30 SRW complete with a 454, 400, and 205. It used to be a diesel, so that means it has the hydroboost setup on it. It also has the chrome 205 shifter. I was thinking of buying it for the D60, then swapping a D44 or 10b back in it's place and re-selling it as a K20. He's asking $3800 for it right now, but that's without me hearing it run and driving it and the driver's window being left down for a long time. I'm thinking I can talk him down to $3000. What do you think the resale on it would be if I yanked the D60 and put something back in it's place, given I tell people that the 60 is no longer in the truck?
