Vortec 4200 Rear Sump Wing-Style Oil Pan (Pre-order NOW!!!)

Low-profile. Baffled. Built to fit where others don’t.

This hand-built, TIG-finished oil pan is designed for GM Vortec 4200 swaps that require maximum ground clearance without compromising oil capacity. Built and tested on a 2005 Nissan 350Z chassis, it’s perfect for custom applications where stock pans simply don’t fit. Despite its low profile, it still holds a full 7 quarts of oil, just like the factory GM pan.

⚙️ Craftsmanship Details

Each pan is precision-welded by a one-man shop in Lake Elmo, MN using:

• MIG-welded flange for maximum strength at the engine interface

• TIG-welded pan body, baffling, dipstick tube, and return fittings

• Custom rear sump pickup tube, modified in-house from a 5-cylinder pickup — extended and bracketed to bolt directly into the 4200 block

• Ships with new hardware for mounting the pan and pickup

🛠️ Oil Drain Location Options (Included)

You choose your preferred drain configuration:

• Default (recommended): Rear-center wall – best for ground clearance

• Optional: Body-mounted – allows direct inspection of the pickup

🔧 Each pan includes a welded M12 x 1.75 drain bung in your chosen location, and comes with a black steel magnetic drain plug by Racetronix — helping to capture harmful particles before they reach your engine.
