geotek Posted April 25, 2003 Share Posted April 25, 2003 My parts car is a 5-speed, '79 280ZX 2+2. I wanted to use the diff for my 240 v-8 conversion. I'm not ready to use it, yet, but I wanted to see what the rear ratio was. On the cover nameplate it says '397'. As far as I know, it should have a 3.7:1. What does the '397' mean? Does it have anything to do with the ratio? I guess I could spin the tire and count the drive shaft revolutions, but is there an easier way? (always looking for an easier way- usually it ends up being the HARDER way) George Quote Link to comment Share on other sites More sharing options...
