thats exactly correct. at 70 mph with 3.23s you should be close to 2000-2100 rpm. if your converter unlocked that would cost you 4-500 rpm so that would put you at 2500K and with 3.73s at 70 mph its about 24-2500 rpm also.

Yea guys I'm sure it is 3:73s. It's kind of a hassle because I ordered them, yet it's a relief knowing I don't have to go through the process of putting gears in. Oh well now I have more money for mods. Thx Guys.
