Never gave it much thought till one day my brother suggested we put something together for 6 cyl drag racing, something to do upon retirement. Then it clicked. I remembered the Chevy fastback we co-owned in high school. Then thought back to the pioneers of early dry lakes modifieds,the NHRA gasser wars,Kay Sissels beautiful roadster battling the Ford sixes. Also the sound and simplicity and the look, and the challenge. Probably not one reason, but all of the above. At amost age 60 I tore down my first engine several months ago to use to set up the car. What a blast.And it just keeps getting better.
