to give you an idea, with 3.73s im running 86 mph in the very bottom of 3rd in the 1/8 and at the very bottom of 4th im at 112 mph in the 1/4 but im moded up too though with a 306. i know i run through 1st and 2nd preety quick and thats rpm wise not mph. with a t-5 world class.

I'm running 3.55's w/ a Zspec T5. I'm at 2k rpm's @ 70.

It already had 3.55's in it when I got it or I might have gone w/ 3.73's. My next jump will be to 4.10's, but I want the .59 OD gear from the G-Force kit.....

I have 4.10's on my 5spd

i have 3:27 and was gonna go to 355 or 373. heard i wouldn't feel much difference switching to the 355. i need to open the rear up because when i put the auburn in i didn't adjust backlash and it's really loose. figure put new gears in while it's open. 373's can still go on highway right?

I would go with the 3.73s there're so close so why not?I'm happy with mine it will give you alittle bit better edge in Quarter mile.........Good Luck!!
