My brother had a '71 396 Chevelle SS in fire engine red with white bucket seats - beautiful car. His bud's father owned a garage so lots of after market additions made it onto the car. The Holley carbs pumped like little Texas oil rigs. And they proved to move petrol just s fast every time he needed to fill up.Nothing close to those cars. I had my Chevelle with the L88 427, probably the fastest thing I've ever owned. I'd be scared to death to drive something on land at 300-400 MPH!
