Race gas vs pump gas on lower compression street/strip motor

My old 408 with Econo W2 heads ran 9.80’s with BP93 pump gas. Crazy thing about that was I would stop on the way to the track and buy 10 gallons of it and use it in my Duster, quad, and generator. Well when I switched to alcohol in my Duster I would just grab 87 for the quad and generator. They didn’t like the switch one bit and it took some track tuning and cleaning to get them running smooth again. They were spoiled.
