4 valve/cyl LS

Quote
Designed, developed and manufactured in-house, the naturally aspirated, 7.0 Liter engine features Mercury Racing’s exclusive aluminum four-valve cylinder heads and dual overhead camshaft valve train integrated with an LS cylinder block packed with Mercury Racing spec hardware. This proven valve train, which greatly enhances engine durability over a standard two-valve design, enables the engine to produce a staggering 775 horsepower at 7500 RPM on pump fuel.

Too bad they will be expensive as hell.

How are they driving the cams off the crank? I'd guess they're running another chain but where the cam gear covers are they look wide enough for belts and none of the accessories look like they're pushed out any farther than an ls3.
