Chris Craft newest engine

This one comes from Chevy/ GM like many of the classic era engines. It is a powerful engine in a Chris Craft. It acts like a big block but is within the small block family tree.

 

What is different with this engine? The block is aluminum, not cast iron, so it is a light weight package and comes with closed cooling, so the engine internals never touches the water that you boat in. The valve train features VVT or continuously variable valve timing (VVT). Chevy says “Athletes understand that proper breathing is critical to maintaining peak performance under all conditions, and so do Chevrolet powertrain engineers. Getting air in and exhaust gases out of the combustion chamber under all speeds [makes more power]. Chevrolet’s VVT system uses electro-hydraulic actuators between the drive sprocket and camshaft to twist the cam relative to the crankshaft position. Adjusting the cam phasing in this manner allows the valves that are actuated by that camshaft to be opened and closed earlier or later.”

 

Hot Rod magazine says “The beauty of VVT is that an improvement in high-rpm power doesn’t sacrifice bottom-end torque.”

 

Volvo marinized this Chevy V8-380 (and its sister 430 HP version) for Chris Craft. Volvo says “it is the next generation of gasoline engine performance for powerboats. Modern technology and advanced design deliver improved acceleration, impressive mid-range response, reduced fuel consumption, reduced emissions and quiet, smooth operation. All in a lighter and more durable package. This next generation engine is a perfect match for the Duoprop drive, featuring twin counter-rotating propellers.”
