The Camaro ZL1 comes stout from the factory: 6.2-liter supercharged V8 with 580 horsepower. But what happens when Lingenfelter Performance gets ahold of it? Not only did the guys at Winding Road Magazine get to sample a tuner-prepped ZL1 Camaro, but it also was an unusal ZL1 convertible.
What Lingenfelter did was add CNC ZL1 LSA cylinder heads, a Lingenfelter GT9 camshaft, 63 lbs/hour fuel injectors, and a few supercharger tweaks. Horsepower rose to over 700 plus 685 lb-ft of torque. Compare that to the original ZL1 from 1969, which had 430 gross horsepower − that would translate to even less horsepower in today’s net rating system. So let’s add some headers and see what that would be – 560, as the story goes, but that’s still less than the stock 2014 ZL1. Plus the 1969 ZL1 is barely streetable, while the modern Camaro does quite well with the AC running. Still not an apples to apples comparison considering the modern Camaro has been massaged by Lingenfelter? Okay, have Motion Performance do their thing and the 1969 ZL1 would be even less streetable. Yay, modernity!
