rear drive axles

[blazenlow]

im working on puting a 94 lt1 motor and trans into a 92 blazer 2wd and was wondering if the rear axles will handle the added power.

the stock motor is a 4.3 v6 with auto trans

I would upgrade the rear end, the only reason SyTy rear end's hold up is because the power is split in AWD
