guys with 4:10s chime in.

I ran a 3.73 for a few years and I thought it was perfect for the setup I had (maf/tb/manifold/exhaust/pullies). A buddy of mines had the same mods in his GT but also had a 4.10. In the 1/4 we were pretty much a drivers race but on the street and highway his car felt much more responsive(read: better). If I had it to do over I would've gone with a 4.10 from the beginning. I think choosing between the two is just a matter of what your priorities are with the car. You have your answer. I decided to move up to a 4.10 after the heads/cam went in. It is perfect for this combo. I don't mind the higher freeway RPMs because I love the way 5th gear pulls.

I went with a 3.73 in my AOD because I just wanted to wake the car up. I bought this car to be a daily driver/cruiser first but the 2.73 gear just want cutting it. Track car or not this thing was downright depressing in stock form.

i dunno 3rd would spin a little, more roasting action in 1st and 2nd though. I couldnt spin 1st or 2nd with stock gears unless i dumped it.

I am aiming for 400 RWHP n/a and 750 on the spray, with a TKO tranny. Has anyone ran this setup in the 1/8 before? I want to be traping nere redline, but I don't know what gears to get...

Being a guy who's driven 410s for the last nearly 4 years, i'd have to say it comes down to how much power and torque your car makes. The more stock your engine is, the more gear you need, where more power can easily make up for a smaller gear. Of course if you're looking at max quarter mile potential, that's not the case. I have a friend with a pretty stout 347/3.73 car and it's a total animal, and 1st gear is nearly USELESS on street tires. I can't imagine it with any more gear than it has. If you drive it hard enough it'll blow the tires out in 4th gear. If you're looking at a solid stroker or power adders, i'd stay away from anything more than 3.73s unless you're only looking to play around. The biggest down fall to 4.10s is you lose a pretty good amount of top speed. My car has been killed on the highway 3 times now....twice by two different SHO's and once by....a Civic....because my car just ran out of breath compared to the other higher revving cars and just petered out. So many people have 3.73s because they're a good compromise between take off and top end.
