Re: Taking '70 on a road trip - should I swap trannys?

The trans swap is much easier than the gear swap if you plan to put the 4.10s back in after the trip. You could always also get another rear axle to swap in with lower gears which would be a pretty quick swap. Last of all, some good sound deadening could be a quick afternoon project and may help keep the noise down for what will be quite a long drive.


Rear axle swap < 700R tranny swap

Around here they are always on Craigslist in the $100-$150 range.

3:08, 3:4x, or 3:73 will be friendlier on the hwy.

And then you can always switch back.
