Hello

I was wondering what would be the maximum CR that could be run with 93 pump gas and NO DETONATION using:

-55cc closed chamber w2 cast iron heads
-proper 0.040" to 0.050" quench with a 4" crank and dished pistons
-245° @050 street solid roller with about 600 lift.

would 10.9:1 put me in PING territory???
