3.6 track engine
I am building a 3.6 track motor. The CR with .040'' being the deck gap is 11.8-1.0. My deck gap or piston to head clearance on this motor is .060''. So my CR will be less than 11.8. Also I am going to have to cut the intake pockets on the pistons .070'' as I don't have the valve to piston clearance that I need. That drops the CR additionally. To get the deck gap to .040'' bringing the CR up some, will require my cutting the cylinders. Don't know what the desired magic CR should be, but of my two 3.0 motors, the one with the higher CR definitely has more pop. My thoughts/questions; #1, how important is getting the piston that close to the head creating what I have heard called the ''squish'' factor. #2, I can cut the cylinders on either end. At the bottom will require my also cutting the O ring groove. At the top will require additional milling on the surround area of the head so that the cylinder fins don't bottom out. Also the CE ring groove will have to be cut. Is the CE ring needed. Was intended to stem oil leaks I think. any info with experience in this area would be greatly appreciated. Thanks, Bob
