Guest Pegasus76 Posted December 3, 2002 Share Posted December 3, 2002 I don't know what gears the previous owner through in here...But at around 55 mph or so I am already running close to 2 1/2 rpms in 5th gear...What gears should I swap in there to make it a little lower...It's a 73 camaro engine with a 85 t-5 transmission...Stock R200 rear end but dunno what gears he through in there.

fl327 Posted December 3, 2002 Share Posted December 3, 2002 sounds like a 3.90, grab a 3.54 out of any 75-78 280z with an r200 in it, and youll be happy again. Quote Link to comment Share on other sites More sharing options...
Phantom Posted December 3, 2002 Share Posted December 3, 2002 Go to www.geocities.com/z_design_studio/ It is a gearing vs rpm calculator that will allow you to determine what you have for a differential now and what new ratio you would like to have.
