I'm a bit on my own with my 4.1 as my oil pan will be a butchery of 2 to 3 pans to clear the Riviera's Chassis. Right now I have a Buick 350 fullsized pan, a 300 generic pan, a stock 4.1L pan, and a 425 Nailhead fullsized pan. atleast 2 of those are getting combined into the pan I'll use and I'll figure out a baffle off of my final sump configuration.
