Bob Dutro's 1971 "Heavy Chevy" 402 -- I looked for twenty-three years for another 1971 "Heavy Chevy." I did not know how many were made (6727) until the internet was around. I had all but given up hope of finding one again, when in June 2001, I saw one for sale in the "Oregonian." I was the first to call on the ad. I went and looked at it. It needed some TLC. I think I am the fourth owner.
