I realize this is an older thread, but since it contains some inaccurate information I thought I'd add a correction for anybody who comes along later, as I did.
The oil pressure sending unit is NOT on the passenger side at the rear of the engine. It's located on the drivers side almost parallel with the oil filter, either rearward of the oil filter or towards the front of the block. There are two identical threaded oil galley access points along the outside of the lifter valley and either of them could be used for the sending unit although I've only seen them in the rear location next to the oil filter on the forty or so 300/4.9L engines I've worked on.

As for passenger side / drivers side it is best to say left or right and this is ALWWAYS when sitting it the car/truck.
I say this as we have some members from down under and they drive from the wrong side ... the right side so when you say drivers side they would be looking on the wrong side of the car/truck.
We have the same issue in the AMC world as down under also imported AMC's and they drive from the right side also.

I ran a 3rd gen Bronco,300 4spd, 3/4 ton in mud bogs/street . Kept breaking the idler gears,brand didn't matter. Only way to quiet them was to run a seperate oil line to top of timing cover,oil directly to cam gear. Only way to stop breaking gears was to switch to c6 auto. Or quit racing. This combo with stock bottom end, knurled pistons,clifford alum intake ( 600 holley) and ported /polished head/ hooker/flowmaster was dyno'd at 510 hp/640 torque. Building another to run 1/8th mile in a 2wd Bronco 2.
