I have heard there that specific timing covers are necessary for specific water pumps. In particular...
Early Model: Cast Iron Water Pump
Early Model: Aluminum Water Pump
Late Model: Reverse Rotation
I have the original timing cover off of my '66 that I just bead blasted. I compared it today from the one off my '90 5.0. Everything appears identical in the water pump mounting location including the inlets in and out of the water pump, bolt patterns, and depth behind the water pump.
Years ago I replaced my early iron water pump with an aluminum one and didn't know of a difference between the timing covers and ran it for 120,000 worry free miles.
What gives? If somebody really knows the difference, please reply.
Thanks!
