i just got my new 3.73 gears but i haven't got them put in yet and im wondering if anyone knows how much difference they will make at the strip i run an 1/8th mile track


also if anyone has switched from 3.08 gears to 3.73 gears did you notice any difference
 
I just made the switch a little over a week ago from the 3.08 to the 3.73. IMO it made a huge difference in performance. The only concern I had, which I expected anyway, was the lack of traction at the track. I had spinning issues before with the 3.08 but now with the 3.73 there's no luck for me at the track with street tires anymore.
 
After I did my 5.0 stick swap, I still had the 2.73 gear, 7.5" ring gear, and NON-POSI rear end. A month later I installed my fully built 8.8 rear end with 3.73's and it was a huge difference. Felt like I added 50HP or more. You will noticed improved times in your 1/8 and 1/4 performance.
 
I am considering switching from stock 2.73's to 3.73's in my car, but I am scared like you about traction. As it is right now once I hit boost if my tires are spinning they stay spinning...if you drive your car a lot look into some Nitto DR's, they aren't as stick as the MT's but you won't get killed in the rain!
 
for what it's worth, I know different engine... but I had a '97 GT that I switched from 2.73 to 3.73 and it was a complete night and day difference, best thing I had ever did... I now have a 5.0 and am considering 4.10's (anyone here with fox's have 4.10's?)
