This week, we're taking a look at a Muscle Car that proves one didn't need the biggest engine to be a bad machine!    The 1969 Camaro Z/28 boasted a high-revving 302 cube V8 - a size dictated by the SCCA for Trans Am racing legality.    But don't let the relatively small displacement fool you - the Z/28 302 was conservatively rated at 290 HP - although many claim it made closer to 350 HP at a higher RPM than the original rating.    This Dusk Blue example retains all the cool parts that made up the Z/28 package.   From the Brothers Collection.
