Line 19:

The '''LS6''' is a higher-output version of [[Chevrolet]]'s [[small-block]] LS1 engine. It is an all-aluminum 5.7 liter (5665 cc) [[pushrod]] engine and produces 405 hp (302 kW) and 400 ft.lbf (542 Nm) of torque. It is used in the high-performance C5 [[Chevrolet Corvette|Corvette]] Z06 model and the [[Cadillac CTS]] V-Series. The C6 Corvette Z06 will get a new [[GM LS engine#LS7|LS7]].

The LS6 shares its block with the [[GM LS1 engine]], but other changes were made. Improved intake, a titanium exhaust, higher-lift cams, and higher compression boosts output, and a new oiling system is better suited to high lateral acceleration. This LS6 shouldn't be confused with the LS6 454, which could pound out more than 450 horsepower.
