Mexican Super Bee

Do you happen to know when emissions mediation was mandated in Mexico?

IIRC the "270" 318 goes back at least to 1971.
The earlier cars had no emissions at all. You can see by the pictures there is nothing.

Mexico never used the Lean Burn system either.

I haven't been into the engines of the Super Bees to answer your questions, sorry about that.

The super Bee today is very hard to find unmolested, so it might be hard to find out what they did from the factory.

Also, as I am sure you know, there is almost nothing online about Mexican cars so they stay a mystery.

I can help you get one though, if that is what you want.
