I run a true 100% full-flow system on my 32 Cabriolet (284 cubic inch stroker engine). I have a modified oil pump -> The bottom plate of the pump has been modified to take the entire oil volume out of the pump, through a hard-line and bulkhead fitting in the side of the oil pan, through a full-flow filter and back to an enlarged oil galley on the side of the block. The oil-pump casting has been plugged where the oil normally exits the pump gear area and goes through the long-slot to the pressure galley (it was blocked off). Though this setup is a bit more complex that the '95%' setup that many use - it delivers 100% filtered oil to the engine.

I've always snickered at the claim of '95%' filtration for the guys that make mods to pull the oil from the original oil-galleys, then through a filter - the number seems a bit optimistic to me in that these systems pump unfiltered oil to the rear main bearing - so I consider these 95% systems to be about '66%' . . . but hey, we can calculate it a lot of ways. LOL
