scott87star Posted February 8, 2013 Report Share Posted February 8, 2013 Most are hydraulic with flat tappet style rockers, some of the early cars had mechanical clearance adjustment. Although the US cars never had a roller setup it is an aftermarket option so you're going to have to pull off the valve cover to see what you've got. 3:54 rear end was stock, 3:90 is a popular aftermarket option.

Technology Posted February 9, 2013 Report Share Posted February 9, 2013 The cam should be the last thing you modify. the 3.54 gears are perfect for the car. If you change to a different transmission, they may be too tall. Quote Link to comment Share on other sites More sharing options...
