Here comes trouble Posted June 19, 2005 Share Posted June 19, 2005 a 1977 with manual transmission would have the larger R200 with 3.545 to 1 gearing and the auto trans would have the smaller R180 with the same 3.545 gearing ..1977 was the year Z's and others generally got the 5 apeed trans Quote Link to comment Share on other sites More sharing options...
Thumper Posted June 19, 2005 Share Posted June 19, 2005 Here's a website that has all the different rear-ends and transmission ratios. Plus a nice speed calculator with graphs. http://www.geocities.com/z_design_studio/transmission.html Quote Link to comment Share on other sites More sharing options...
