1971 EEC ss454
Any ideas what approx. % of Chevelles/ElCaminos with 454 did not have Evaporative Emissions Control. Was it mandatory to have this on every car or dependent on what state car delivered to .

Re: 1971 EEC ss454
I think nearly everyone of the 454's got RPO NA-9 in 1971.It became a Govt. mandate in all 50 states beginning w/1971-72 models.In 1970,it was mandatory for vehicles sold brand new in the state of Calif. only and certain parts of Nevada.
I have yet to see a 71 454 w/o it,but it could be possible as it was a transition year,and some may have slipped through the cracks.
