3.91v or 3.73lsd

[prezzaman]

I have a 92 325 vert with a 3.91 viscous from my ix parts car, I also have a low mile 3.73lsd, just wondering if there is any advantage to installing the lsd or keep it as is? Thanks.

Other than the obviously slightly lower cruising RPMs and thus better highway mileage, you probably won't benefit much, if at all from installing the 3.73 over the 3.91.

If you put either in, go with the 3.73 for the clutch-type unit. There is a negligible difference between the 3.91 and 3.73 anyway. Hardly noticeable at all.

What he said. For performance driving, clutch type > viscous, no matter how you slice it. Viscous is nice in FWD though.
