Product Details

The McLeod 450300 is a nodular iron flywheel designed as a direct bolt-in replacement for 1955–1985 Chevrolet Small Block engines. Featuring a 153-tooth ring gear and neutral (0) balance, this flywheel is engineered to deliver superior strength and reliability compared to factory OEM units — without the cost and hassle of flywheel resurfacing.

McLeod nodular iron flywheels are manufactured from high-strength nodular cast iron, a material known for its exceptional tensile strength and resistance to cracking under high heat and stress cycles. This makes them a smart upgrade over standard OEM flywheels, which can warp or develop surface cracks over time.

Key Features:

  • Nodular iron construction — stronger and more durable than OEM cast iron flywheels
  • 153-tooth ring gear for proper starter engagement
  • Neutral (0) balance — compatible with 0-balance externally balanced engines
  • Direct bolt-in fitment for 1955–1985 Chevrolet Small Block V8 applications
  • Eliminates the need for flywheel resurfacing — replace instead of resurface
  • Weighs approximately 16 lbs for optimal rotating mass
  • Each unit sold individually

When replacing a clutch, the condition of the flywheel is critical to clutch performance and longevity. The McLeod 450300 provides a cost-effective, high-quality solution that installs easily and performs reliably for street and performance applications.

Note 2

CENTERBORE/CRANK BOSS: Because of standard variances in OEM and Aftermarket manufacturing tolerances, the flywheel to crankshaft boss fit may have variations from slip-fit to slight interference. Interference at the crankshaft “boss” can be corrected by heating the flywheel to temporarily to expand the center bore for correct mounting. Caution, flywheel will be hot, handle with care.
