datzenmike Posted July 16, 2013 Report Share Posted July 16, 2013 I have the overdrive 5 Speed... From 4 to 5 I only drop 500 rpm . It might drop 500 RPMs but you would need to say at what RPM you were at in 4th for this to be relevant. The dogleg for your car has a 14.6% overdrive so 4,100 in 4th will drop 500 RPMs to 3501 in 5th. I would say that with a 3.364 rear end and an overdrive 5 speed you are about a low as you should go. Which trucks should I look out for? Hoping for a lower ratio... Need lower Rpm.. Tired of 65mph at 3000rpm Then lower your top speed. There are practical limits to the lowest rear axle ratio you can run coupled with the over drive ratio. At some point you would have to admit that the car cannot sustain a cruising speed of 60 with the engine at idle. Keep in mind that.... A car traveling at 30MPH needs four times as much power to push through the air at 60MPH!!!!! Quote Link to comment

alexmeans Posted July 17, 2013 Author Report Share Posted July 17, 2013 Dang then I got luck with my set up then... Did the 521 or 620 come with a z24 (carbed) and a 5 Speed? Quote Link to comment
datzenmike Posted July 19, 2013 Report Share Posted July 19, 2013 No The '81-'82 had Z22 and the '82-'86.5 had Z24s in the 720. In the S110 (200sx) the Z20E was used in the '80-'81 and the Z22E in the '82 and '83. Z24s were also used in the D21 Hardbody through '89? and in the Vanette. Quote Link to comment
