To keep the four-year-old Chevelle in the muscle car race, Chevy had to do
something to swing the balance back in its favor. After some brainstorming,
the product planners came up with a simple answer-more cubic inches under the
hood. Chevy announced that it would be releasing new 454-cid big-block V-8 and
the resulting model was called the SS 454. The LS6 was a super-high-performance
engine featuring things like four-bolt main bearings, nodular iron bearing caps,
heavy-duty connecting rods, big-diameter exhaust valves and a solid-lifter
camshaft. A test car powered by the LS6 engine moved from 0-to-60 mph in
5.4 seconds and did the standing-start quarter-mile in 13.81 seconds at 103.8 mph.

This particular example was restored by Floyd Garret in the late 1990s, purchased
by Dan Jensen of Pure Stock Drag Racing fame, and is now part of the
Larry and Rachelle Weymouth Collection.
