[QUOTE="ANGREY, post: 15804334, member: 188865"] I've seen other discussions about running 411's but never going smaller than the stock 373's. Going smaller would make the car even more difficult to launch/start than it already is. These cars are fairly difficult to launch with as wide as the gear ratios are to match the wide rpm range and the steep torque curve at the bottom end. Too much RPM and you spin. Not enough and you bog. Very tight window, but obviously not what the car is designed to do. My car runs like 87 at 2500 rpm in 6th and 103/104 at 3000 rpm. That's plenty of gear. Running 411s would reduce the time between gears and make the shift cadence more like most "traditional" manual V8's. I see so many guys short shifting because they're used to the pace of rowing of cars that redline in the mid 6's. I happen to like the overdrive and tranquility of the 6th overdrive. Running 411s would definitely liven the car up a bit, but for long(er) trips, you'd definitely notice a drop in fuel economy (all driving conditions) and for those of us with aftermarket exhaust, you'd need hearing protection for long trips cruising above 70.
