Shes working pretty good as the MPH shows less power than the ET does. Signs of a good working combo...

Any thoughts on this ... 3.90 gears vs 4.10 I have both sets ..

I’m just curious about how many times a year do you race 1/4 mile. That would help me make up my mind. Beautiful car and fast too.

Fran I really don't think you would see much of a difference from 4.30 to 4.10s Car is still amazing with a full interior and a 9 inch tire. It really shows how much you work to get this car where it's at. Let me know when you want to do the gear swap you know I'm in Nice pass dude it gets faster every month. Gus

Any thoughts on this ... 3.90 gears vs 4.10 I have both sets .. My advice would be the 3.90 gears. I don't think you'll see enough difference with 4.10 gears to make it worth the time it takes to swap gears. Put the 3.90 gears in there and see what she does. I think it will pick up a little top end speed and the ET won't change much. It really depends on the torque converter. The 3.90 gears will loosen up the converter a touch which will change some things. It could make the car quicker or slower depending on how the chassis reacts. You might have to adjust the shocks or the tire pressure to keep it launching hard.
