Fast burn heads deliver race-winning power Chevrolet Performance’s 23-degree Fast Burn heads have large, 210-cc intake runners and 2.00/1.55-inch valves, along with specially shaped combustion chambers that make quick, efficient work of the air/fuel charge. When partnered with an aggressive, high-lift camshaft, you’ve got a great balance of horsepower and torque — and that’s exactly what you get with the CT400 racing engine. The foundation for the CT400 is our SP350/385 crate engine, including a sturdy iron block with four-bolt mains, a forged crankshaft, and high-strength pistons. We’ve tuned the CT400 for more power, rated at 404 horses and 406 lb-ft of torque. Rounding out the package is a racing oil pan with a dual kick-out design, as well as a valve cover breather kit, special aluminum roller rocker arms, a single-plane aluminum high-rise intake manifold, and balancer. You add the water pump, carburetor, starter, distributor, spark plugs, and wires.
