CarlG, I decided to answer your question in the PM here in case someone else was wondering. My oil filter is a positive, full flow system. All oil is forced through the filter and then back in the oil channel above the pump and follows it's normal path from there. It involves brazing an additional boss on the side of the block and blocking off the top of the pump to force the oil out the opened up original boss, through the filter and back in the additional boss above the original. The bracket is just some 11 gauge sheet and an aluminum block. Ron W
