70 TA challenger tri power

didnt norm have a tri power?

Yes he did.
The air cleaners he used are worth crazy money now.
I actually have one.
I sold the 6-pac with intake and carbs to a guy quite a few years back but the guy did not want the air cleaner because it said tri-power.
It was years ago way before the internet, It could have been the real MR. Norms set up.
I think I sold it for 200.00 in good condition.
Kept the air cleaner, it is screwed to the wall of my garage as I type this, it is real nice never painted, but is covered in dust.
