I'm pretty sure you can still find it at specific stations near a track or something.

They were transitioning to unleaded fuels around the early 70's
Guess- unleaded fuels made less power, also carburetors, and drag racing for fun wasn't frowned upon as much as today. Lean it out=more chance for knocking, but more power. Higher octane= more power and less chance to knock.
E85 gave me ~10-15hp over 91. Imagine a car with 2x the cylinders and 3x the displacement. 20-30hp from switching to high octane doesn't sound too unreasonable.
