    Had them in my 10 bolt and still had plenty of gear left. I would go to 4.10's or even 4.30's like myself in my new 9" I love the gears for the street and when my H&C combo go in I might need a 28" tire for the track.

    I ordered the 3.90's a while back, havent got here yet there made in italy and i guess theres a big need for them, anyway ive heard they are great for the 6-speed, you should see better times with the 3.90's vs. 3.42's

    Your better off just going to 4:10's. They will yeild better times if you can hook up with them. If not you will just spin harder off the line. From a roll they are badass though.
