BBC Orange Oil Pan

The TRANS-DAPT BBC Orange Oil Pan (model 9921) is a direct replacement rear sump oil pan engineered for big block Chevy engines. Built for enthusiasts and professional mechanics who demand OEM-style fitment without compromise, this pan maintains stock depth dimensions while delivering the reliable capacity and sealing integrity required for street, strip, and high-performance applications. The distinctive orange powder coat finish provides corrosion resistance and visual appeal under the hood, making it a practical upgrade for engine rebuilds, restorations, and performance modifications.

This 4-quart steel pan features a two-piece seal design that ensures a leak-free installation and simplifies future maintenance when pan removal becomes necessary. The rear sump configuration positions the oil pickup in the optimal location for gravity-fed lubrication during cornering and acceleration, a critical design feature that prevents oil starvation in performance driving scenarios. Its stock depth profile allows the pan to fit within standard chassis clearances, eliminating the need for custom headers, exhaust modifications, or frame notching—critical considerations when you're working within tight underbody tolerances on big block swaps or vintage builds.

This pan is the standard choice for big block Chevy engine installations across 454, 427, and 396 builds, whether you're restoring a classic Chevrolet truck or tuning a street machine. Technicians favor this unit for its straightforward drop-in design, eliminating the guesswork and custom fabrication that can derail a build timeline. At 9.87 lbs, it's light enough for weight-conscious builds yet robust enough to handle sustained high-RPM operation and sustained track duty.
