I speak from sad personal experience with the slabe sided Cobra
oil pan shown above. If you are going to track your car, get a pan with baffles. I now run an Aviad on my NEW engine. VIR , where SAAC will hold the national meet next summer, has many elevation changes and I destroyed a main bearing, etc. by
oil starving the engine with the slab sided pan. I ne3ver had any trouble with other tracks, but they didn't have the elevation changes with the curves at the same time.
