Ed Pitts' post inspired me to do something similar - draw off the block do a bypass through the filter and then dump back into the sump - except I tapped the timing cover instead (easier to remove for the drilling and tapping).

I mounted mine higher because of the splash shields. You may wonder... I used SAE 30R7 hose with 1/2" steel springs wound around it to avoid crimping in the bends. Pressure shouldn't ever be a problem.
I'm getting a full crankcase oil change every 15 minutes at idle.
