B.ZSSY Weld-In Motor Mount Kit Pack of 2 — Universal SBC/BBC 350-454 Compatible, Heavy-Gauge Steel Powder-Coated

B.ZSSY weld-in universal motor mount kit provides a durable, weldable mounting solution for small- and big-block Chevy swaps, fitting SBC/BBC 350, 396, 454 and 4.3L V6 engines.

When you’re doing an engine swap or fabricating a custom frame, choosing a reliable motor mount set is critical. This B.ZSSY kit includes two weld-in mounts, hardware and frame plates engineered to accept common small- and big-block Chevrolet engines. Built from thick steel with a smooth powder coat, the set is meant to simplify alignments while providing a strong connection between block and chassis.

How does this mount kit fit SBC and BBC engine swaps?

The design matches common mounting locations and bushing dimensions used in many small- and big-block Chevy installations, letting you adapt older or custom frames. You weld the bases to the frame rails and bolt the mount to the engine or crossmember as required.

• Compatible with SBC/BBC 350, 396, 454 and 4.3L V6 engines.
• Includes two weld-in mounts, two bolts and four frame plates for adjustable placement.
• Mount hole diameter 0.50" and bushing length 1.81" for standard fasteners.
• Overall height 4.13", base length 4.08", base width 4.28" for planning clearances.

What materials and construction should I expect?

B.ZSSY uses 0.25-inch thick steel for the mount plates to balance rigidity and weldability. A smooth powder-coat finish helps resist corrosion and removes sharp edges that can injure during handling or installation.

• Heavy-gauge steel construction for durable load support during operation.
• Powder-coated surface improves corrosion resistance and handling safety.
• Weld-ready base design for secure attachment to a variety of frame rails.
• Bushings sized to accept common engine-mount bolts for simple assembly.

How does installation work and what hardware is included?

Installation is a mix of welding the mount bases to the frame and bolting the mounts to the engine or crossmember. The kit supplies core hardware and removable frame plates so you can test fit and finalize placement before completing welds.

• Package includes: 2 weld-in motor mounts, 2 bolts and 4 frame plates for orientation options.
• Frame plates let you mock up location and ensure correct engine height and angle.
• Weld tabs allow customization—grind or trim as needed to match chassis geometry.
• Designed for use with standard engine-mount fasteners (hole diameter 0.50").

Will these mounts handle everyday driving and custom builds?

These mounts are made for regular street and light-duty performance use typical in engine swaps and project restorations. They provide a solid platform for alignment and can be adapted for heavier duty with additional reinforcement if required by a high-power build.

• Suitable for street-driven swaps and most custom chassis applications.
• Weldable bases give you freedom to add gussets or reinforcement where needed.
• Powder-coat prevents premature corrosion in typical automotive environments.
• Pack of two mounts covers both sides of typical V6/V8 engine installations.

Who is this for: This B.ZSSY weld-in motor mount kit is aimed at DIY restorers, custom builders and professional fabricators doing SBC or BBC swaps (350, 396, 454) or installing 4.3L V6 engines. If you need weld-ready mounts that align with common engine bolt patterns, include basic hardware and let you control final position and reinforcement, this kit provides a practical, cost-effective solution.
