Picked up a 72 in Nebraska last weekend, Motor is ok, but growing tired and leaky. I can't park in the drive until it stops per the wife./forums/images/graemlins/rolleyes.gif I have a 72 motor I built 10 years ago it has about 1K miles on it. I started the disasembly for inspection yesterday. Looks like I will need the heads cleaned up as some surface rust has come into the intake side. The exhasut was caked with carbon. Anyone done a motor swap on the early years Blazer? Can one provide any expiences/gotchyas? I will probably be doing this myself, mabe my brother or 1 other friend will come by when I need some extra hands. Webpage: Truck homepage Any help is good help, thanks!
