I've been trying to figure out what engines the Chevelle 'Cowl Induction' option was available on. For 1970, it was available on the SS-396 and SS-454, no mystery there.
However, for '71-'72 all the literature states that it was only available with the 454. I have heard quite a few claims of 402 and 350 cars with factory-installed Cowl Induction. I'm not sure which to believe.
If anyone has some pertinent information or observations, I would like to hear it, thanks !
