Moroso GTO Oil Pan for LS Engine Swap
Whether you are grafting an LS engine into a vintage Chevy frame or customizing a street machine, the Moroso GTO Oil Pan stands ready to manage oil in tight spaces under factory crossmembers. Its low-profile sump and precision machined flanges allow direct mounting to GM blocks without adapters, cutting installation steps and reducing alignment concerns. By routing fluid through internal baffles toward the sump and using a rigid pickup tube girdle, this pan keeps oil feeding the pump during cornering or heavy braking. Every aspect of the design supports consistent lubrication and engine bay clearance in LS swap projects.
Precision Mounting Flanges for Direct GM Block Interface
The Moroso GTO Oil Pan features precision CNC machined flanges that bolt directly to GM LS blocks without the need for adapter plates or spacer kits. This direct interface ensures the gasket surfaces align perfectly, reducing the risk of oil leaks and providing a reliable seal under high pressure. By removing the complexity of extra brackets, the pan cuts installation time and prevents misalignment issues that can compromise engine performance. The uniform flange thickness also distributes clamping forces evenly across the block rail, which helps maintain hardware integrity over repeated service cycles. Installers can expect a straightforward fit on factory block mounts, ensuring consistent results across a variety of Chevy and GM chassis.
Engineered Internal Baffles and Pickup Tube Girdle Stability
The internal baffle system of the Moroso GTO pan uses a network of guide plates to direct oil toward the pickup during cornering, rapid acceleration, and heavy braking. These strategically arranged walls hold fluid in the sump area, preventing pressure drops that can lead to bearing wear or pump cavitation. Integrated into this design is the pickup tube girdle, a rigid brace that secures the pickup in a fixed position and maintains correct depth for optimal oil flow. By channeling the oil along predetermined paths, the pan also enhances heat transfer from the fluid to the casting walls, helping control operating temperatures. This combination of internal dynamics delivers reliable lubrication and pressure stability, even under demanding driving conditions.
Cast Aluminum Construction for Strength and Heat Management
Constructed from a robust cast aluminum alloy, the oil pan resists dents and corrosion that can undermine thinner steel designs. Aluminum's high thermal conductivity draws heat away from circulating oil, accelerating cooling and extending service intervals. The pan's thick casting walls and reinforced mounting rails withstand engine vibration and high torque loads without distortion, preserving flange flatness and sealing performance. Following the casting process, each pan is precision machined to ensure true flatness on all sealing surfaces, matching factory GM standards. This material selection not only offers lasting durability but also supports consistent oil temperatures for reliable engine protection.
Low-Profile Sump Contoured for Classic Chevy Frames
The low-profile sump features a sculpted front nose designed to slip beneath the factory cross member structures commonly found in classic Chevy and GM frames. This shallow section maintains ground clearance and avoids contact with exhaust pipes or frame rails, which is critical in tight engine bays. Beyond the cross member the sump deepens to provide adequate oil volume for sustained high rpm operation without risk of starvation. The contoured shape allows the engine to sit lower in the chassis, preserving underbody geometry and maintaining proper driveline angles. As a result, the Moroso GTO Oil Pan supports seamless LS conversions while ensuring consistent lubrication in limited spaces.
