does anyone know the standard comp ratio of the 80 srx? We're doing a rebuild and are considering new pistons. Any advice would be appreciated. Thanks, Ed (newby)

why does my buddies 80 srx have 170 in both cylinders.... it appears to have correct heads on it.....Guage has been tested against other guages and is good...I keep reading that thses sleds have around 140 or so, but that sounds low for an old school race engine. I dunno....something is strange here.
