Default Going from 3.73s to 4.10s

What kind of gains would i see going from 3.73s to 4.10s. Freeway driving isnt a big deal as we dont drive the car but 50 miles a month. Right now with the 3.73s the car has went with the fuddle 3500 and all mods in the sig 1.63 60' and 12.2@112 at +5000DA. I just added the crane 1.8 Rockers and with 4.10s what could i expect at the 60' and overall quarter mile. i want to get to the 11s at our track with the bad DA.

I wouldn't on an auto car. The 1st gear ratio is best using a 3.73 pinion, 4.10's will yeild small gains especially if you have a convertor too.

I'd not waste the money on those gears, I'd sell the rockers and spend $200 on a used cam in the sale section and $169 on a set of Comp 918 vsprings, with $100 going to hardened pushrods. If you can do the install yourself great or pay somebody $400 to do it.

You'll have 30+ hp with a cam and THAT is something you'll feel. Forget the gears with your set-up. -Joshua
