Donovan Engineering’s “Woody” talks about their new bottom-end design that combats Top Fuel’s most common failure: thrown rods. Close ups show a clever, modular girdle that cuts downtime between runs, and drop-in sleeves continue to offer ultra-quick repairs for cylinder bore failures.

The insider’s “cement trick” is discussed with Bob Santoro, and main-cap hard anodizing brings to light how dissimilar materials can be used successfully in this high-stress environment.

Ever popular in Vintage Drag Racing circles today, this 160-lb block continues to set records and dominate the scene across the nation at these events.

With this new upgrade, the venerable 417 Legend lives on, and is available now at DonovanEngineering.com.
