  That's been a Chevy problem ever since they offered V8s in their cars  
  and trucks. It's not necessarily a 'starter' problem, but a low voltage  
  problem due to the way they run the power. While Ford runs their battery  
  cable to a remote solinoid, GM mounts the starter solinoid to the starter.  
    
  GM's solinoid exciter wires have to run to the ignition switch, then to  
  the solinoid, where they get heated up by the exhaust running too close to  
  them.  
    
  The fix is to use a Ford remote solinoid to alleviate the voltage loss  
  across the GM solinoid. Of course GM won't do that, instead they put heat  
  shields on them.  
    
   RN> I think they encased it in a protective wrapping of some kind or  
   RN> installed a heat shield, but my memory of that is vague.  
    
  They used an asbestos wrap in the early years. Now they use a die cut  
  sheet metal shield. Which is interesting, because the shield heats up and  
  transfers the heat to the starter, defeating the purpose of the shield.  
    
  The best fix for this is to route the exhaust away from the starter, which  
  is what they've done since the mid-eighties. On my 56 Chevy, the exhaust  
  header pipes exited the center, thus running 4 hot tubes next to the  
  starter. I re-engineered that exhaust by using 1995 truck headers, which  
  gather at the back of the engine and run down behind the starter next to  
  the bell housing.

  Bet it will fire right up if someone takes the time to change oil and  
  coolant, maybe put in a set of plugs and wires.
