I am still running the factory dual sump pan on the 351W crate engine in our coupe and have run it on the track at R&G as well as the autocross,
oil pressure never budged. The pans were behind in delivery when I assembled the Coupe and is still sitting in a box. I may or may not install it. It's nice, but I think the moving baffle plates seem kind of heavy and have no issues with the stock pan since we primarily use it as a touring car.
