427 cubic inches of American iron. 435 HP “from the factory,” but almost all Le Mans-bound Corvettes were tuned to over 500 HP. 4 barrel Holley carb, slamming 103 octane racing fuel into 8 cylinders for the forged pistons to get very angry with it and make it explode.
The result is a rumbling, barking, snarling beast of a car, with side port exhausts and barely any baffles. At idle, it sounds like it wants to bite your head off for standing too close.
However, when under wide-open throttle, it howls like a wild animal, unleashed to chase down its competition.
Even more impressive, in this video from the Zandvoort track in the Netherlands, is that despite being around things such as a Lola T70, a McLaren M1B Can-Am racer, and even a Ferrari 365 GTB/4 Daytona Competizione, it howls louder than any of them. And McLaren’s of that age are not known for being quiet or reserved!
