Both oil pumps would rely on the motor to be up to full speed at 1140 RPM to reach normal pumping capacity. With the finger style pump, full capacity is about as much force as the oil dribbling out of the top oiling hole that feeds the spin bearing, after it had ran for several seconds. Photo taken during a rebuild of a '56 mechanism with an original style oil pump back in '08 at Greg's.
During the rebuild of the '58 I attempted to take the same photo, but instead oil was literally shooting 5 to 6 feet away from the oiling hole and across the room, rather than this "dribble". With this in mind, even if the motor is only rotating at a fraction of 1140 RPM, the two piece spring/vane pump is definitely delivering oil up through to the bearing.
So yes, the oiling passages do indeed carry oil through the drive shaft, up through the reciprocating mechanism, through the pulsator shaft, and ultimately out the spin cage oiling holes.
