CA smog differences on \'75 350 as opposed to \'80\'s 350 iam interested in purchasing a 1975 longbed on here in California. I know that the smog on my '81 was a hassle and i had to fix a few things. On this '75, there arent as many emmisons controls. can anyone do a compare on older smogged vehicles and 80's smogged vehicles? any input is appreciated.
