12 bolt moser w/3.90 or 4.10
#3
i went from 4:10's to 3:73's and now i plan on getting 3:90's. i have a full bolt on car with a 12bolt and HC. i couldnt get traction with the 4:10's even in third gear sometimes and 3:73's dont have the punch i was used to. so i think 3:90 would be a good split.

4.11's here with the same cam. still under 2000@70, but you will need a good susp. setup to hook, and a really sticky tire( no drag radials). with street tires no traction till 3rd, but when it hooks it pulls like a ****! i'm thinking of stepping down in gear only because of n20. love the 4.11's!!

All depends on what you are looking for.
I had 390's in a car. top speed in 4th gear @ 6,700 rpms was 133 with a 26" tire.
My cousin has 410's in his. top speed in 4th @ 6,600 rpms is 119 with a 26" tire.
Same dyno was used for results. I would say if you are not going to break 120mph in the qtr. use 410's if your are going to run faster look to a taller tire or go with the 390's

I've got 3.90's now but I'm switching them out for 4.10's when I install a spool. Our cars couldn't be more different though and I'm looking to wring every last .001 out of my car at the track so take that into consideration. I also plan on running either a 26.4" or a 27" tall tire.

I have 4.10s in my Moser. I was wondering if 3.73s will give me better street drivability. I had 3.73s in my 10-bolt and loved it. What do you think I should do.
I don't to the track much and drive to work everyday. No hwy miles though.
