If you’re looking for the biggest bang for your muscle car buck, look no further than the Callaway Camaro SC630. It starts off as either an LT1 or SS with the naturally aspirated 6.2-liter V8 before the aftermarket specialist throws in a custom supercharger, high-flow intake, intercooler. These upgrades take the engine well above its stock output of 455 horsepower and 455 pound-feet (617 Newton-meters) of torque.

As the name of the package implies, the Camaro SC630 has 630 hp on tap, along with a mountain-moving 610 lb-ft (827 Nm). These are numbers that get quite close to the 650 hp and 650 lb-ft (881 Nm) available from the supercharged V8 LT4 6.2-liter engine inside the ZL1, but while Chevy’s supercharged Camaro costs $64,695, Callaway’s car is under $54,000.

The tuner will also throw in a carbon engine cover to sweeten the deal, along with branded floor mats and door sill plates for your amped-up Chevy.
