How much to shim oil pump?
I did a search and found 3 different answers.
Some say .100 minimum, LME supposedly recommends .150, TSP shims theirs .080. Which one is going to be best and not wash out bearings. Im going to fully port my oil pump with my dremel tool but I would like to bump pressure up a bit, I was at 65psi at 6600 and with my 4.100 stroke crank I want a little more lubrication and Im running large oil tolerances too, to help with the loading form the big stroke crank.

Pressure also helps with lubrication and Im running large oil tolernaces due to an extra long stroke crank and I just want to make sure the life blood of my engine is circulating well.

i ported my stocker and took the shimms out of my f'd up tsp pump got about 70psi at 500rpm's and havent really reved it much so cant tell you on the wot pressures.
edit: i also got rp 10w 30 in there so the pressure going to be a good bit higher then m1 10w 30 .
