Product Details

The McLeod 563220 is a high-performance aluminum flywheel engineered specifically for 1968-1998 Big Block Ford 429-460 engines in the 385 series family. Weighing just 15 pounds, this lightweight flywheel dramatically reduces rotational mass compared to factory cast iron units, enabling faster engine response and quicker acceleration throughout the RPM range.

Key Specifications:

  • CNC machined from premium 6061-T6 aluminum for precise tolerances and durability
  • Zero balance (0 bal) configuration for proper engine balancing
  • 176-tooth hardened 1045 steel ring gear for reliable starter engagement
  • Replaceable steel friction plate for long-term serviceability
  • 15-pound weight for significantly reduced rotational inertia

Performance Benefits:

  • Ideal for supercharged and turbocharged applications where quick throttle response is critical
  • Allows engines to achieve rapid RPM levels with less effort
  • Perfect for high-horsepower builds and race applications
  • Reduces driveline stress during aggressive shifts

McLeod's precision CNC machining process ensures proper balance and friction surface preparation, while the replaceable friction plate design allows for future maintenance without replacing the entire flywheel assembly. This flywheel is an essential upgrade for any serious Big Block Ford performance build.

NOTE:

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.

Autoplicity had the best price I could find on an Invidia downpipe for my 08+ Subaru STI. I had to pay for shipping but the total price was still well below their competitors who advertised free shipping.<br><br>Thanks Autoplicity!<br>Matt

I hope you're right about compatibility!!!!

They were very help full and got me the best price possible.

They had the product I wanted at $20-$30 cheaper than anywhere else I could find. With free shipping as well. Wonderful company, will definitely buy more products from them.

Hard to find part, in stock, and the best price around. Amazing!!!

Price was right!

"Wow. Great Price and extremely fast shipping. I had a CS question and they replied promptly and satisfactorily. I will definitely buy from Autoplicity again."

Great products and great prices! Highly recommend!
