Bob Dutro's 1971 "Heavy Chevy" 402 -- I have seen only two 1971 "Heavy Chevy's", and I have owned both of them. The first one was a high school graduation present from my parents in June 1971. It had a 350 ci, Muncie (M20) four speed, power disc brakes, and power steering. It was lime green with black interior, and cost $3250.00.
