Build story
This is the car I always wanted back when they came out, but couldn't afford. These cars always handled well, but compared to today's sporty cars they lack the horsepower to be competitive, so I decided to build the car the way Chevy should have. I now have a nice handling car with a better power to weight ratio than a Hellcat Challenger and is dependable enough to drive 140 miles round trip to the drag strip and run mid 7's in the eight mile naturally aspirated all day on pump gas.
