Also what ones would be the best?

 

Link doesn't work on this forum either. "Gears" questions belong in "Drivetrain", not on LT1/LT4 Engine Tech. I'll move it to "Drivetrain" for you.

Using the part # rather than the link, those are Motive 4.56's for a 7.5/7.625" 10-bolt, 3-series carrier. They will fit in your stock rear. Gonna run out of RPM real fast in 4th gear with 4.56's and virtually no mods.

 

Link is fixed

 

Now it makes sense..... 4.10's, still correct for your 3-series 10-bolt. The Motives will probably be quieter than the Richmonds.

 

Thanks just ordered the motives should be in tomorrow or th next day.
