EBIDX%3AIT Ken.............Depending on the dish of the piston, between 7.3-7.9:1.  Pretty low.viewtopic.php?t=24954 I've read somewhere people shaving the block 1mm to raise the compression while using vitara pistons. Because that's the distance the vitara pistons keep from reaching the top of the block._________________
