Engine will be built in the Tonawanda Engine Plant, which is where the original 1955 small block was built. Engine is 99.9-percent new.
2014 Corvette will have 450/450 preliminary rating, 465-pounds. "More than 26 MPG".

11.5:1 compression

Direct injection system hidden under the intake manifold. Injector flow rate is 22.0cc/s@10MPa, up to 2,175psi (15MPa). 65-volt fuel injector controller. Highest flowing pump on the market and it is driven off of the camshaft with a unique lifter system. Each injector has 6 holes and they are all angled.

Increased based displacement allows the engine to stay in 4-cylinder mode more often, resulting in more power and torque with increased fuel consumption. 62 crank degrees of cam phasing authority on the CVVT camshaft. Four-into-one cast short-tuber header, that is nearly equal length.

Variable-displacement oil pump will adjust oil flow to maintain proper oil pressure at the bearings. 50-75kpa lower oil pressure than the Gen4 LS engine. Wet and Dry sump available.

"Swapped intake and exhaust"
"One VERY big intake and one modestly sized exhaust valve"
"Twisted shaped high-flowing intake and exhaust ports"
"Centralized spark plug"
“Buried the pump and injectors in the valley to reduce 'click' from the DI system at idle.”
“Deck height is the same, rod length, stroke and bore are the same. Crank to cam centerline are the same."
"We hope it is very difficult to crack the computer code."
"There will still be LS crate and service engines being built. No more further LS engine development."
