Stock? Hi Pressure? Hi Volume?

I also have to much pressure with the High volume pump on my 360 engine, causing it to leak around the oil filter gasket during each pass. 100+ lbs at high rpms, 65 idleing hot, with 30 wt oil. I 've tried several different filters and even reinstalled the 90 degree adapter. I was thinking about going back with stock pump. I know several people that run stock pumps in their race engines with no problems.

Mrmopartech could you explain how you set the spring for 60 lbs on the small block pump with out having to pull the pan more than once. Thanks
