What rear end?
Justin
If the factory torque arm is mounted directly to the housing without an adapter bracket, it can only be a stock 10-bolt or an aftermarket 12-bolt. Those can be told apart visually, as the 12 is physically larger.

frankie...
if there are 10 bolts, check brake lines, see if they are in some clips that are permanently fixed to the axle tubes, and the piece that connects the flexible brake line to the steel line is actualy bolted to the housing.
if there are more than 10 bolts, or there are zip straps or soemthign else holding the brake lines on, its probably not the stock rear end.
If it looks like it has been replaced but has 10 bolts and the brake lines are on right, its possible the previous owner broke it and replaced it with another stock one.
with a picture ill bet 99% of the people on this site could identify it in 10 seconds...
as for the engine size, it is a 346, but its very commonly reffered to as a 350.
