Re: 89 4 speed questions
My sm465 with a 30" tall tire and 4.10 rear gears would turn almost 3000 rpm at 65 mph.so I put in a 5spd and dropped it to around 2200 rpm at 65mph.. If you know all the info this is a quick way to find engine rpm............http://www.crawlpedia.com/rpm_gear_calculator.htm
