Performance Engine Balancing Services for Big Block Engines

Performance engine balancing services are critical for big block and heavier rotating assemblies where vibration, internal stress, and component mismatch can quickly affect durability and performance. At Benning Auto Parts, we provide precision balancing for big block Chevy, Ford, and Chrysler engines using a CWT 5500 digital balancing machine and a target of +/- 1 gram.

Proper balancing helps reduce damaging forces inside the engine and allows the rotating assembly to operate more smoothly and efficiently. This is especially important in larger-displacement, performance, and higher-RPM builds where imbalance can place greater stress on bearings, main saddles, and related components.

Why Performance Engine Balancing Is Important

• Reduces vibration and internal stress
• Improves smooth engine operation
• Supports bearing life and durability
• Helps protect your investment in high-value engine parts
• Important for big block, stroker, and performance engine builds

What We Balance

• Crankshafts
• Connecting rods
• Pistons and rings
• Rod bearings
• Harmonic balancers
• Flywheels or flexplates
• Pressure plates and bolts for manual transmission applications

Our Performance Engine Balancing Process

1. Inspect and measure the rotating assembly
2. Calculate bob weight based on your actual components
3. Mount the crankshaft on our CWT 5500 digital balancer
4. Identify imbalance and correct weight distribution
5. Verify final balance numbers and provide a balance sheet

Important Note on Rotating Assembly Changes

When changing rotating components such as pistons, rods, or crankshafts—especially in performance builds—incorrect component selection or mismatched weights can affect the calculated bob weight used during balancing. Planning your rotating assembly correctly from the start can help avoid unnecessary expense and support a smoother balancing process.
