441-incher built by John Shields in 1959 for a race boat customer who never picked it up. Restored by the late-Don Tognotti, it has been on display in his Sacramento speed shop for decades. Here's a Hilborn-sucking Potvin blower mounted to the flywheel end of the engine with a Cragar bellhousing and Pribble (Cad specialists back in the day) mounting plate. The other end of the engine has a polished aluminum timing cover and a chromed billet-steel damper that was machined to drive the propshaft."
