just got a set of the 116 cp pistons in yesterday really good bang for the buck. not an al out race piston by any means but a good economy piston that puts compression into a 360, the main thing they are missing. I just weigh one they are so close to the stock piston weight you can just go ahead and run them.


thanks for the replies guys.
So what CR would the 116s have with EQ's "Magnum" heads? (62 or 63cc chambers) We will go with either Victor or Fel Pro "stock Replacement" Magnum engine head gaskets.

One other concept that has been getting alot of press all over is "quench" I guess more quench means more CR before better fuel is needed to prevent detonation. but I don't quite "get" how you get the quench and exactly what it is.



Depends on your deck height. That piston at "0" deck, with a .041 gasket and 63cc chamber calculates to 10.7:1

.050 in hole, calculates to 9.5:1
