Road racing punishes oil systems hard: sustained cornering loads starve stock pans of lubrication at the worst possible moment. Moroso's 351W rear-sump oil pan keeps oil where the pump needs it through every corner, braking zone, and acceleration point your Fox-body or Fox-platform Ford will ever see. The 7.5-inch depth and 7-quart capacity give the engine a meaningful reserve over the factory pan, and the rear T-sump layout suits the original sump location of the 351W without relocating pickups or modifying the block.
Diamond-shaped four trap door assembly. Four trap doors arranged in a diamond pattern work alongside a removable anti-slosh baffle to keep oil collected at the sump under lateral, longitudinal, and combined loading. Remove the baffle for drag racing applications where straight-line acceleration is the only load; leave it in for road racing and autocross where oil control in all axes matters.
Full clearance for stroker builds. The pan clears a 4.0-inch stroke with most steel connecting rods and clears all 4-bolt main caps, including front and rear mains. Builders running a stroked 351W in a vintage Mustang, Thunderbird, or Capri can fit this pan without grinding the casting or trimming the windage tray.
Fully fabricated steel with billet end seals. The main structure is fabricated steel finished in Moroso's own black powder coat for corrosion resistance. Billet end seals replace the rubber or cork pieces that compress and leak over time, giving the pan a reliable seal at both ends of the crankshaft. A 1/4-inch NPT dipstick provision and a 1/2-inch NPT oil temperature bung allow direct instrumentation without adapters.
