Gear Ratio and RPM deciding on gears

I want a hot street car that I can take on the track a few times a year at most since I don't have a lot of money to replace parts etc. But I would like to be able to ride a decent torque curve around town and the torque of the 340 starts above 3000 probably more like what I show in the graph at 3800. Wouldn't 4.11's have more torque around town than a 3.55? I don't plan on leaving the Phoenix metro area and tour with. I DO want performance and the 2.71 I have is a dog with the torque converter as is. I plan on working with Lenny AFTER I get the rear ratio in. There is always a split on what rear gear ration is best. All I know is I have a 904A 3 speed trans that idles at 35MPH lol which is not good.


What do you not have any power under 3000? Seriously, that makes no sense.

You may need to work on your tune up or something.
