Pete,
Just to reiterate, my Canton "road race" pan has the diagonal trap doors. It does not work at all. I can do the NASCAR "tire warming" zigzag maneuver on street tires and cause the
oil pressure to drop...
I have set the pickup as specified. More than once.
I have met with Canton at the PRI show and quizzed their personnel endlessly. I conclude they have no data to support their claims, and worse, don't have a clue about how to fix the
oil pressure loss!
It
is a big block, so my experience may be irrelevant to yours.
I have also seen small block cars lose
oil pressure at Sebring. Also mod motors etc etc. Dunno what pans they used, but they don't seem immune.
I have the idea that other factors are possibly more important. If I knew what they were, none of us would lose oil pressure LOL
I do conclude the way to go is Accusump at the least, and a dry sump as the ultimate.
Had to be said,
Tom
