2.76 vs 2.94 gearing

The 7 1/4" big bolt rear axle is great for that.
AS long as you're not hammering the throttle, the 7 1/4" axle lasts and lasts. A few things that kill them is sudden shock loads like peeling out on a loose surface then onto pavement. The rotational movement suddenly slows way down when you gain traction and all that momentum can blow out the differential. Manual transmission and 7 1/4" axles are not a good combination if you're making any power.
