   Nawwww. He wasn't a bad person to deal with and was doing his best to make   
   sure that his 'show car' was as original as it could be. Can't blame him   
   for wanting it that way.   
      
   Under the hood was a tri-power 389 with the fuel lines meticulously kept   
   in the factory configuration. Although it would look and work better with   
   a custom fuel line setup, he wouldn't budge from the factory config.   
      
   Whoever he was buying parts from sent him Chevy pushrods and rockers. He   
   was not a happy camper when that happened.   
      
   FYI, the difference between Chevy and Pontiac rockers is that the Pontiac   
   rocker balls are adjusted so that the ball rests on a shoulder on the   
   rocker stud. Chevy rockers 'float' and usually have pushrod guides to keep   
   the rocker on the valve stem. Pontiac pushrods are kept in alignment   
   by a smaller pushrod hole to guide them. Late model Chevy rockers still   
   'float, but have a pair of dimples on both sides of the valve stem to keep   
   the rocker on the valve stem. Meanwhile, the new LS engines use an   
   individual rocker mounted on a shaft, eliminating all of that floating   
   business.   
      
   What happens when using Chevy rockers on a Pontiac is that the valves were   
   adjusted like a Chevy; turn the rocker nut down until that rocker becomes   
   quiet, then adjusting the rocker nut a full turn. Pontiac valve adjustment   
   is; turn the nut down until the ball stops the nut from being adjusted   
   any further. Both methods work, but the Pontiac method is more precise and   
   with Chevy rockers, it will sound like it has a solid lifer cam in it.

   We had that type of storm cell pass through here a week ago or so. I swear   
   that lightening hit somewhere in my back yard, but no sign of it anywhere.   
   Andrew woke up to the same hit, I think, and the old church across the   
   street from his house was on fire. That hit took out computers and set   
   fire to electrical facilities inside. They held a yard sale and there was   
   a really nice desk there that had smoke damage to it, but was fine   
   otherwise. I didn't need a desk.
