427 S/O,
I do not understand your explanation.
The top hole on the engine block from the motor is that going to the "IN" of the filters?
Also, the bottom hole of the block
oil filter adaptor - Does that go to the out of the
oil filter relocator
Also for other post I am getting (assuming) 10 -15 on my stewart Warner gauge and with a cheap mechanical gauge. When I drive I only get max 27 -29 psi.
