A 1968 Camaro convertible rolled into our Naperville shop wearing SS and RS badges, carrying a small block Chevy and a recent round of upgrades. Under the hood, the original combination had already been replaced with aluminum heads, a camshaft, and Holley EFI...
At Fluid MotorUnion in Naperville, we pay attention to patterns in airflow, sound, and dyno behavior. Recently, a third gen Camaro with an LS3 swap came into our shop already making 392 wheel horsepower through long tube headers and a reputable aftermarket exhaust system. On...
