Long time lurker....posted for a while when I had my '83 K5 but a buddy blew the motor up and that was the end of that. Now I'm looking at an '87 K5, 6.2, 4x4 for $750 needs a starter. I've also got my name on (though I don't have it yet) a '93 MFI 6.5 NA diesel. Now I'm busy thinking over some possibilities and have a few questions... - what compression is the 6.5 NA going to have? - if I wanted to turbo it, could I add a turbo from a 6.5TD and leave the NA IP alone? - If not, will a turbo IP just bolt in? Or could the NA pump be rebuilt to work with a turbo setup? - are 6.2/6.5 motor mounts the same between the 2nd gen k5 and 3rd gen P30 van? - Do the 6.5 NA heads have the same reputation for cracking/leaking as the 6.2 heads did?
