What brand Ring & Pinion are you running in your 8.75 rear?

What brand/ratio ring and pinion are you running in your 8.75 rear axle?

This 340 (10:1 compression) A-Body Mopar will most likely see a majority of time on the street and some strip. Case is a 489.

I have run 3:23 and 3:72?and 4:10. 4:10 is a bit much, but the best gear for me. 3:72 or 3:91 for street car leaning towards 3:7, I run yukon gear 4:10’s IIRC. but there is only a couple of manufacturers.

Mine is a 3.91 ratio. I'm running a 31" tall tire and a TKO-600 (5-speed).
