The L6 and V8 clutch Z-bars [bellcranks] are different too. I believe the L6 Z-bar is shorter because there is a bracket that bolts to the block and holds the pivot ball out to meet it. On the V8s, it screws into the side of the block directly.
[On 4x4s at least.]

My guess on why the 292 has the passenger side positions for fuel pump and motor mount reversed is that maybe the forward mount gives better resistance to torque wanting to pull the higher block over to one side. Just a guess.
