The oil pressure is directly affected by the water temperature. The CHAMPION 3 row aluminum will take care of that and is much cheaper than the 3 row staggered copper ones.

Also, we shim the oil pressure relief valve 5-6mm( located on the back of the oil pump housing and held in place with a split pin; it can be done with the distributor removed and using careful tapping out of the split pin into the distributor shaft hole). Originally, the pressure relief was spring loaded for 55 psi, much too little for a 7000 rpm engine.
keep us posted, bruce, Red racer
