Gears & Axles - 3 tenth ET drop going from 2:73 to 4:10`s

We sold the car and got it it back with broken spider gears. Replaced the carrier and put in 4:10`s. No other changes went 3 tenths quicker. 13.64 to 13.34. Even picked up some MPH. Time for a stall. Then ditch the factory tires and rims for stickier rubber. Also a tune.

Thats a nice gain. I would think you would pick up an even bigger gain going from 2:73 to 4:10 but .3 is good

To tell the truth. I thought if felt way stronger on the street, but the track times dont lie.

That's great! A good converter will shave .5!!!

Thanks for the comparison, I'm debating right now between 3.73 or a set of 4.10, and I think you have made up my mind as I'm rolling with some 3.23 right now.

Since my car see's limited street duty I just wonder if I should 4.56 this thing and pray the 10 bolt holds for a couple of passes.

We are seriously thinking about a Yank stall. We drive it to the track an hour. Race. Then drive home. Dont like the 2200rpm @ 60 mph, but that is the trade off we were will to except. What stall would you recommend. We want the stall before we tune it. We will also be adding a trans cooler to aid in hot lapping it at the track not to mention help extend trans life alittle. Mid 12`s with bolt on is our goal. We will be calling Yank with our combo to get the correct one. We might add NOS way down the road.

Nice! Got 2.73's here too with only a couple bolt-ons running 12.90's @ 108 in '1700 DA, looking for 12.50's once i put the 4.10's in

What converter do you have? and what are your mods?

stock converter, mac midlengths with catted y, hooker CB, slp lid, free ram air, toyo TQ DR's on stock wheels, still on stock tune, full weight t top car minus spare and jack

1.93 60's

I would get at least a 3600. I had a PTC 3600 for a while and liked it until I got a 4000 Yank and hadn't looked back lol.

Traction is our main concern with a 4k stall. We dont have to many chassis mods yet. Maybe we should consider that before we get the stall. Our best 60ft is 2.10 walking it out of the hole. The track sucked all night. What should our 60ft be with our set up?

With great traction should we be getting 1.9x`s for 60 ft?
