Thanks for the info guys, I'm pulling the pan off this weekend and installing a H/V Melling
oil pump with a H/D pump shaft and while i'm at it, checking the main bearing clearances with plastic gauge. The reason for all of this is to get idle pressures up from 17 lbs to 20+ and when taching 5-6 G I'd like to see 55+ from the current 38 when hot. Also changing the restrictive
oil filter adapter to one made be Beaumont Metals that is far better relieved than the stock unit.
Thanks to Brent for parts help on the pump and shaft...
