[QUOTE="black4vcobra, post: 14323222, member: 82394"] I have 4.10s but according to my calculator, with stock size tires, 4.56's and at 75 mph, you will be at 3038 rpm. That is for a T45 transmission though with a .67 5th gear and the 3650 in the 01s is the same ratio. I could email you the calculator if you wanted to toy with it and put in different gear ratios and tire sizes. Acceleration will be improved down low, your car will tear through the first 3 gears but you will only be going 85 when shifting into 4th. 1st gear will be pretty useless unless you have great tires, otherwise they will just spin on the street. I put in 4.10s when I was N/A and it was a great gear overall. Now that I have a Vortech blower, I wish I had gone with 3.90's. [/QUOTE]
