BBC Oil Pan Black

The TRANS-DAPT BBC Oil Pan Black is a rear-sump oil pan engineered for big block Chevy engines, delivering OEM-compatible capacity and installation reliability for street and performance builds. This 4-quart steel pan addresses a critical cooling and filtration system requirement—proper oil return and sump volume—making it essential for any BBC rebuild, swap, or restoration. Whether you're freshening a classic muscle car or maximizing flow in a modern performance platform, this rear-sump design maintains stock depth geometry for seamless integration into tight engine bays.

Constructed from heavy-duty steel with a black powder-coat finish, the BBC Oil Pan resists corrosion and thermal stress inherent to high-RPM and sustained-load operation. The two-piece seal design simplifies installation and service—critical when future maintenance demands pan removal without full gasket replacement. Stock depth configuration preserves ground clearance and avoids the geometry conflicts that deep-sump designs introduce, particularly important in lowered vehicles or applications where underbody clearance is marginal. The 4-quart capacity balances adequate oil volume for cooling and pressure with practical weight distribution in competition and street environments.

Mechanics and engine builders favor this pan for big block Chevy applications ranging from 454 and 427 mills to period-correct restorations and modern LSX conversions where BBC-pattern geometry is retained. Installation is straightforward on engine stands or in-vehicle, with the stock-depth profile accommodating most suspension and frame configurations without modification. Verify your specific BBC variant and oil pump pickup tube compatibility before ordering; this pan pairs seamlessly with TRANS-DAPT gasket systems and OEM-style dipstick assemblies for comprehensive cooling system assembly.
