Three liters, 380 horsepower, and a 9000 rpm redline. Those are the specs for this Corvair flat six. Now listen to how it sounds.
This naturally-aspirated Corvair-powered dragster runs the quarter in 8.82 at 145 mph, but who cares when it sounds this good.
Bangshift has a great writeup detailing the restrictions on this build for the car to meet its class. Restrictions! As if it wasn't bonkers enough, it's mad to think there's more on the table with this car.
