[SEL] Hercules power unit

[Steve Gray]

Per Hercules, the ZXA was a 2 1/2"  x 3", while the ZXB was 2 5/8" x 3"  
as of July 1957. Only differences between the two were the block, head 
and pistons. Pistons ordered could be CI or Aluminum, and 3 different 
heads could be ordered: standard 6:1, 4000 Ft elev. 6.9:1, and a 7000 Ft 
elev. 7.5:1.
