WOD Old Style 3-Bolt Chevy Motor Mount Plates (Pair)
WA121067
The WOD Old Style 3-Bolt Chevy Motor Mount Plates provide a strong, weld-on foundation for mounting traditional Small Block Chevy (SBC) and Big Block Chevy (BBC) engines into custom chassis. Precision laser cut from 1/4" high-strength steel, these engine mount plates are designed around the classic GM 3-bolt motor mount pattern, giving builders complete freedom to fabricate custom engine mounts, tube structures, or boxed brackets that position the engine exactly where it's needed.
Unlike fixed bolt-on engine mounts, these universal weld-on plates allow unlimited flexibility for custom builds while maintaining the factory 3-bolt mounting pattern. Whether you're building a rock crawler, rock bouncer, Ultra4 race car, prerunner, hot rod, mud truck, or custom engine swap, these are the same style of fabrication components trusted by professional chassis builders.
Includes:
- (2) WOD Old Style 3-Bolt Chevy Motor Mount Plates (Sold as a Pair)
Note: These are weld-on fabrication components intended for custom engine mount fabrication. Welding, mounting hardware, and final engine positioning are required.

FAQ
Why use weld-on engine mount plates?
Universal weld-on engine mount plates allow builders to create engine mounts that fit the chassis—not the other way around. This makes it easy to optimize engine placement for driveline angles, firewall clearance, oil pan clearance, steering components, suspension geometry, and weight distribution.
Precision laser-cut for accurate fitment
Each plate is laser cut to ensure accurate hole placement and consistent dimensions. This simplifies fabrication and provides a precise starting point for custom engine mount construction.
Perfect for custom fabrication
These plates are commonly welded to DOM tubing, boxed steel structures, or custom brackets to create strong engine mounting systems capable of handling the demands of high-horsepower street and off-road vehicles.
Built for custom projects
Whether you're restoring a classic Chevrolet drivetrain or installing a traditional SBC or BBC into a tube chassis, these weld-on plates provide the flexibility and strength needed to build a clean, professional-quality engine mounting system.
