I was always told you want a high volume
Pump not high pressure. Maybe dry sump Ls type
is different. I had a high pressure in one of my Poncho
motors and it washed the bearings.
Pantera has a high volume pump that the engine builder
prepped before installing with an Aviad pan With a mech
gauge shows 60 psi almost all the time. Motor is 10 years old
and sees track and autocross turns at 7500 rpm with steady pressure
Best motor I have ever had and I have lunched over a dozen
in my lifetime. But it is a dart Ford
. Flame suit on
