Re: Improved Cooling

Howard,

These may have been discussed before, but I missed it.  At any rate, our
discussions were always left open ended without your documentation to let us
know where the changes stopped.  Thanks for the info.  If I understand this
correctly, the head castings are the same as non-improved, so if the slots
were milled in non-improved 345 heads they could be used on an improved 392,
correct?  Of course, freeze plugs would have to be added to the water tube
holes.

 Crankcase--water openings in the front wall for entry of water from the
 water pump rather than into the cylinder heads with new water pipes used.
  Water slots were incorporated into the crankcase at the rear of the top
 deck.
 
 Cylinder heads--slots added at the rear to align with the slots in the
 crankcase.
 
 Cylinder head gaskets--slots added (at both ends so it can be used on
 both sides of the engine).
 
 Intake Manifold Gaskets--the water opening port located between the 3rd
 and 4th cylinders on each side was blocked off with only a small, about
 3/8" hole left.
 
 I don't think there's anything here that hasn't been discussed before,
 but this should clarify what the changes were.
