Other versions certainly had their strong points, but the 1970 Chevrolet Camaro Z28 was simply the best all-around Z28 ever built. It was a muscle car that had come into its own. Camaro kept its 108-inch wheelbase this year, but otherwise underwent wholesale change with a new coupe body that was an instant classic. The Z28 returned as a $573 package, the heart of which was a new engine. Trans Am racing now allowed destroking to achieve 305 cid, so the Z28 appropriated the Corvette’s 350-cid LT1 V-8 as its sole power-plant. A timeless small block, the LT1 had solid lifters, a hot cam, big valves, aluminum pistons, 11.0:1 compression, and a 780-cfm Holley four-barrel. It was rated at 370 bhp in the ‘Vette and 360 in the Z28.
