<VV> Combustion Chamber Modification

[Mikeamauro@aol.com]

The Greenbrier's 110 is out for a major rebuild.  The time is ripe to 
reconfigure the heads to reduce engine tendency to knock and ping.  My version of the 
Technical Manual is 1986; while it has some good info on this topic, there 
must be more current information out there.  I also have Bob Helt's latest book 
(presently out on loan)...is there anything there?  My goal is to end up with 
9:1 compression ration, but burn regular or mid-grade fuel (87-89 octane); is 
this a pie- in-the-sky dream?  The vehicle is already equipped with Safeguard 
knock control system.  Also, what is the chamber CC for a 110 @ 9:1?  Any info 
available would be appreciated.
Thanks,
