## Discrepancy

UPON DISASSEMBLY OF ENGINE, FOUND WRONG PISTONS INSTALLED.  RECORDS INDICATE PISTONS SOLD AS PART OF A TOP OVERHAUL KIT WITH CHROME CYLINDERS (4/1994).  CYLINDERS REMOVED FOR GLAZING AND 3 PISTONS WERE SCORED ENOUGH TO REQUIRE REPLACEMENT.  REPLACED ALL 6 WITH CORRECT SET OF BALANCED PISTONS.
