I bought a 1972 454 LT5 corvette in 78. It had a canister. Can't recall if there was a pump. I don't think federal cars had them as I had a set of headers on it without air injection. Miss that car.

In NY up until a few years ago all pickups had to have commercial plates . Even little Toyota pickups . And you couldn’t use them on the parkways . This got changed with the popularity of trucks .

Over 400 ci had less emission controls in them . I had a 68 AMX with a 343 4spd that had a smog pump . I also had a 1971 401 Javelin 4spd no pump . And few other emission items were not on that car .
