how Much Compression for 2.0 Litre
 

I have a stock 2.0 litre and am wondering what the stock compression should be and what would be an acceptable variance from cyliner to cylinder. I seem to have lost my little pocket tech specs book. thanks for the help

Dean;
My spec book (covering all '69, 70 and 71 models) calls out the following spec's for all of those models and years. I suspect that yours should be close to this.

"9-11 kp/cm^2; maximum deviation between cylinders up to 1.5 kp/cm^2 (about 15%): tested with engine oil temperature of 60 degrees C minimum."

Does anyone have the conversion from metric to US units?

that would be rougly 130-155# US. an S would pump more that a T. throttles open, strong battery/starter function.
