How much quicker will 3.73's be?

[stephen4785]

Im gonna be putting in a 9inch with 3.73's and a limted slip. How much quicker in the 1/8 or 1/4 will it be. Not an exact time but what generally? I dont have any track times. I can tell you that the motor puts out around 290hp(desktop dyno projection). Thanks for any help.

It would help if we knew what you old gears were....

We don't know what gears you used to have or how fast you used to be. But generally speaking a classic stang with ~300FWHP and radials should see the high half of the 13s assuming decent driver skill and traction and no major parasitic power loss. YMMV of course
