There is no manual for this.

Old style factory dry sump.
What are the ins and outs of this setup?

2 An12 & 1 An10 on the pump, breather on the plate, two holes on the oil filter.

I have a remote adapter (An12) for the oil filter location on the block (from Speedsource) to a remote filter & oil tank, also two oil coolers running in parallel off T's

Are the oil coolers best plumbed just before going into the engine?

 

Ok, the in is the lower 12AN fitting which comes from your oil tank, the mid fitting is the pressure out put that goes to the rear cover housing and the top one 10AN goes to the oil filter and then to both oil coolers if using two then back to the oil tank. Hopefully this will help.
