3:55 gears to 323 gears

The difference will be quite noticeable.

I just swapped in a 3.23 for a 2.94 in a B-body with 15" tires. I noticed the difference just backing out of the garage! :)
...and how did the performance change.I am thinking of using 2.94 in place of my existing 3.23
...stock 340 and 14" tires.
