The new Camaro is pretty stout in stock trim with a fat 6.2L LS3 V-8 lurking underhood. If stock is stout, then modified will be better. We decided to throw a few common upgrades at a manual-trans LS3 SS to see what kind of power GM left on the table for the aftermarket. We took this Victory Red SS to BBK Performance in Temecula, California, and spent a day putting on and tearing off parts and flogging the car on the dyno each time.
