Question Rear end questions

I have limited knowledge when it comes to rear ends. I've not really had to do much work on them beyond what I've done in this thread (replaced axle bearing, seals, welded on the Ridetech 4-link brackets, cleaned and painted).

The rear end that came with my car is an 8.2" 10 bolt, NON posi, with 2.73 gears. I'm aiming for 400 hp/torque from the SBC400 I'll be rebuilding and have a close ratio Muncie M21 4 speed transmission.

My concern is that the non posi, 2.73, rear end I have now is going to be too mild to really use/feel/enjoy 400 hp/torque.

I may have a lead on an 8.5" 10 bolt, posi, with 3.42 gears, with new Timken bearings throughout.

Any thoughts/suggestions/guidance? Questions to ask the seller?

Daniel
