There are different oil pumps for the big Cadillac engines. One faces forward from the block at a 45 degree angle downward. The next faces downward 45 degrees and points right toward the bottom of the crankshaft pulley. There is another, that has been described as pointing more outward than the first one described. These can all be interchanged, but make very sure to properly clean the oil pump and block mating surfaces and always use a new oil pump gasket. The correct gaskets are available from major gasket manufacturers, and should be about 0.005" thick. An oil pump gasket that is too thick will cause more oil to bypass the pump gears and allow more end play of those gears too, something you do not want. | There are different oil pumps for the big Cadillac engines.

| − | The stock Cad oil pump spring can be shimmed using a Q-jet metering jet to boost oil pressure to about 50-60 psi. 10-12 psi per 1000 rpm is good. Make sure to prime the oiling system using an electric drill to spin the pump after you do this to check for proper operation of the pump and pressure bypass and to check the oil pressure psi. | + | The stock Cad oil pump spring can be shimmed using a Q-jet metering jet to boost oil pressure to about 50-60 psi. 10-12 psi per 1000 rpm is good.
