I ran thru a calculator the best I could and it is telling me when using advertised data on the web that the compression will be in between 10.9 to 11.6 ish. again playing with head gasket thickness. if I use a .060 head gasket its 11.6 to 1, if I use the .075 its 10.5 to 1. if I use a .090 its in the 9's. simple but still crazy. I have read these are very tolerant to higher compression. they have to be with all the boost these guys are putting to these motors.
I know the tune is everything. I am learning daily about these motors. completely different then my old LA motor.
