Whoa there yourself, Paul.... this thread concerns a 300 Hurst... made in
1970 with a 440 RB motor. The oil pump is external and a piece of cake to
remove and replace. No need to remove the pan.

WHOA THERE Folks, before you try dropping the pan to get at the pump,
Please think about what folks do to prime a fresh motor.
Get a Priming rud/tool, poping out the distributor is WAY easier then
dropping the pan and going after the pump. a few miniutes with the
electric drill and the priming tool will tell you something at least!
