Re: big 10's anyone?

Wow. You guys have been busy...

I don't have anything to add, other than to say California did have more stringent emissions regulations that "Federal" emissions regs back then (that's why there were differing engine RPOs. Incidently, these days more and more states are signing up for California style requirements). I can't comment on Canadian regs, but back then I thought they followed US Federal regulations.

My baseline is that '75 was the first year for Cats on a 1/2 ton Federal truck. California may have been different than that, and "bigger" trucks would follow after that.

As was mentioned earlier, the "Big 10" was an option that was added to the existing truck (ie, Scottsdale or Silverado), just like the trailering option could be added without changing the trim level.
