My little smallblock makes 1002 hp and want to try a 2.10 1st gear in my Dart. 4.30 Pro gear.
Just got a new NSX 8" Billet converter and thought it might be better than the stock 2.48 1st gear.
Whats your thoughts?


Car will be much more manageable and fun to drive with the 2.10 low.
You don’t say how much it weighs.
A friend struggled - better yet fought his car off the line making 1K + horsepower. Would wheel stand when it got hold of the track, ran 8.50’s. Tried 2nd gear launch and that helped a bunch and only lost about a tenth.

Eventually tried a 2.20 low and that sun gear lasted 30 runs.
After failing a second sun gear he stuck a PG in it. Says it was the best thing he ever did to the car.




The car weighs 3450lbs.
I tried a 1.80 1st gear and lost .5
It was a dog.
Not sure how much better a 2.10 would be over a 1.80.
I'm sure a 2.48 would be perfect.
But the new transmission came with a A1 2.10.
I hate pulling transmissions so trying to do it right the 1st time.



Shame on me for not asking before - why do you want to change from what you have. What issues are you having ?




Bought a Rossler Turbo 400 3 speed ProMod transmission and it came with a 2.10 1st gear. I tried a 1.80 years ago and it was just a turd.
I'm sure a 2.10 isnt much better. 1/8th mile heads up racing is what I do primarily.
I need as much 60 foot as possible to be competitive.

Cab as you can see I bought a Turbo 400
