Don't be afraid. It won't feel much different when you're just daily driving. Most of the difference will be felt at highway speeds or when you're punching it.

When I first transitioned to 4.10's It felt as if it was shifting through the gears very fast. It would be in 4th gear at 35. I got the xcal3 tuner and had it custom tuned shift points and it's good now!

I had them in my car for about 2 years and still would have them but was maxing them out at the track. They are a great gear and really woke the auto up.
The only thing I didn't like was highway driving with them (70+mph). The drone was bad and my RPMs were WAY up there. LOL

I originally bought 4.10s but quickly called and changed my order to 3.73s. I'm very happy with my all around performance. I can chirp 2nd with ease and burn thru 1st without an issue. I cruise at 80 on the highway and my RPMs are around 2,800.

I have 4.10s on my blown auto and they are perfect. I installed the blower first with the stock gearing and it was still slow off the line, the 4.10s made about as much difference as the blower itself.
Still wish it was 5 speed though.

you have 3 gears to use, if you have 26" tires or even 28" tires and are running very high traps, then you run our of "gear" as in you almost or do hit redline in 3rd before you cross the 1/4

No... I know what it is when you run out of gear I'm saying how is he not running out of gear with 4.10s and a blower.

like i said, his trap is so high the 4.10's are maxing out his 3rd gear before the end of the track.

Ah..ok got it.
ahah it was my bad, you said "not" run out of gear. 28" tires helps. To lengthen my top speed in general i think i put in a .92 servo gear in with the build instead of the stock either .96 or .98 which makes my 4th gear go up as high as stock rear gears about. But you dont use 4th gear at the track.
From all the years I have been on this forum, most people recommend the 4.10's for an N/A auto. You have made the right choice.
I went with the milder 3.73's b/c I lived in NY and felt it would make it easier for me to drive through snowstorms/ice. (Which I did many times.) If it was totally free, I'd go with the 4.10's right now.

Easy, I dont go to the track
Its strickly a pleasure vehicle, no real interest in drag racing it.

They are awsome on centri cars too!
He would have to be trapping 120+mph which I don' think he is/would be, I just maxed mine out last year. I was actually getting ready to throw my 4.10s back in because I had a built auto put in but after seeing my car on the dyno I think I'm going to have my hands full with the 3.73.
I should be trapping in the 13Xs this year and be into the 10s. Easy, I dont go to the track
Do you cruise in Ft Wayne much on Saturdays? I should be at Hauls next Saturday with my new setup.
you should stop by.BTW Did you ever have Bob install those gears?

Yeah I cruise around every once in a while. I was screwing around last night since the wife was working.
Ill probably be out tonite since its supposed to be nice. If I see your car I will stop by and say hey. But yeah Bob installed the gears.

Ive got 4.10s in my 3650 but I would imagine 4.10s would make even more sense for an auto being that one of the disadvantages of 4.10s and a manual is that you are shifting a lot.
