The early 1960s saw American automakers building some very special and very limited editions of production models that appeared to be stock, but were hiding some tricks to make them race-ready.   This 1962 Chevrolet Impala Z11 is just such a car.  A factory-built lightweight racer, this car features a high-performance 409 engine and aluminum body panels to reduce weight.    The restoration was debuted by Jim Mattison at the Muscle Car and Corvette Nationals in Chicago.

The Brothers Collection is home to an armada of muscle Corvettes, and this one… well it's over the top.  Sure, 1959 was far before the official muscle car era began and it is America's sportscar, but this fuel-injected crown sapphire roadster is sporting the hottest performance goodies underneath its mesmerizing exterior.
 

Some say one way to characterize a high performance engine is to compare the ratio of it’s output in horsepower versus the volume of its displacement in cubic inches.   Anything over 1 horsepower per cube and you’ve got yourself a high-perf machine.   Our ‘67 Corvette Roadster sure looks the part, but how does it measure up?   Check this one out from The Brothers Collection.  
 
Our Muscle Car Of The Week from the Brothers Collection is a 1970 Chevrolet Chevelle, built with the SS performance and styling package.    The Chevelle was the midsize Chevrolet family car, and the SS option added a long list of performance upgrades in the driveline and suspension departments.  Ours was also built with the Regular Production Option code LS-6, the high-compression big-dog 454 cubic inch V8.   Could this be the very last 1970 Chevelle SS LS-6 454 ever built?
