The dry deck motors go back many years. I have a 948 one that was first
built in 1968 and raced through 1972. It has slightly hemi dome pistons
(now .045 overbore) with corresponding cutting into the head to allow a 0
deck height. I have run it occasionally in vintage racing and it remains my
favorite motor of all time, although the cam grind and its pure 1970
legality make it uncompetitive with todays "vintage" 948s.
Getting the copper rings cut and fitted was always a chancy proposition for
me. More than once I fired the motor after a head freshening and would have
to pull the head and start over making new rings -- one of the rings would
have popped out of it's groove just as the head was seating down and ruining
the seal.
In a new shop I'm building, I plan to clean up and repaint this motor, and
then just display it on a stand. It'll be a fitting end for a very old
friend with a lot of good race miles on it.
