After a product shoot at Donovan Engineering, “Lister Bob” Santoro got Norman “Woody” Woodruff to chat about some amazing features of his new Lightweight HC400 block.

Those who grew up in the musclecar era already know about these coveted Donovan blocks. In case you missed it, this clip offers a little insight into the design philosophy that led this mill into the winners circle more times than not.

Bob growls in disbelief when Woody reveals the oiling secrets of needle cam bearing design.

Priority oiling is covered along with the advantage running of a tall deck. Beautiful close ups of the CNC millwork is shown in great detail. Woody even discloses the reasoning behind the clever sleeve flange design that keeps things in place.

It’s a Zen-like revelation, and even Woody could hear the monks chant…though he tries to ignore it.
