Hold on now Turbos!! If you haven’t run 4.10s maybe you should hold your comments.

I run several different ratios 3.27, 3.73 and 4.10s. I think they are great, maybe the best ratio for the typical street cobra application with one caveat: you need to run a sticky tire.
You guys should all know by now, this game is all about the tire! If you run T/A radial (or similar rubber ilk), it doesn’t matter what gear or how much HP you have, you can incinerate them in 1st and 2nd gear. Climb out of the automotive dark ages and get some capable tires. But I digress..

Roger,

4.10s will provide slightly better acceleration over 3.73s. You will pick up 200-300 rpm on the highway @ 65-70mph depending on the 5th gear ratio you have.
Changing gears in an 8.8 isn’t hard but it does require the tools and knowledge to set the thing up correctly. Unless you are going to do many, take it to a local shop and have it done. The last one I had done (here in LA) ran me about $200+ parts with the center section out of the car.
