clutch linkage ? - Hemi/BB - A-body

"Z-bar is level in car and parallel to the frame - I have seen many BB A-body with the z-bars very crooked in the car - maybe this is why ?"

Chassis guide say's "torque shaft (z-bar) should be mounted straight across from frame to bellhousing in any view. "

So if it's not you need to adjust the bellhousing pivot to get it straight first.
