High-Reving Performance Lap after Lap

Chevrolet Performance’s high-revving CT400 racing crate engine uses aluminum Fast Burn cylinder heads with LS-style beehive valve springs to enable greater high-rpm performance and durability. They allow the engine to rev higher to make the most of every cubic inch of air drawn through it, helping it produce 404 horsepower at 5,600 rpm and 406 lb.-ft. of torque at 4,600 rpm.

The CT400 also has a tough bottom end, anchored by a forged steel crankshaft and strong aluminum pistons installed in a brand-new block with four-bolt mains. It also features a racing oil pan and a single-plane aluminum intake manifold. Add your carburetor and other finishing components to get the CT400 running in your race car, so you can chase the checkered flag!
