CT400 Crate Engine
400 hp @ 5,500 rpm / 400 lb.-ft. @ 4,500 rpm
High-Revving Performance and Durability!
Chevrolet Performance’s CT400 racing crate engine now features Fast Burn cylinder heads with LS-style beehive valve springs that 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.
The beehive springs are part of the lightweight aluminum cylinder assemblies, which are based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves. 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.
The assembly also includes an open-plenum high-rise intake manifold, a racing-only 8-quart circle track oil pan with a dual kick-out design, a valve cover breather kit and aluminum roller rocker arms.
