This is Anthony Wang's Testa Rossa (#0722).  Its very distinctive engine is below.	Here's Bruce McCaw in a 4.1 liter 335-S (#0764).  Can you see the differences?
The name "Testa Rossa" comes from the (always) red-painted cam covers on these engines.  These 3 liter Single Overhead Cam (SOHC) designs produced 300 HP.	Here's McCaw's much wilder engine.  This 4.1 liter  features Double Overhead Cams (DOHC) on each bank of cylinders -- hence the nickname "4-cams" for these near 400 HP units.
