My 70 Pontiac Bonneville with a 455 HO only runs well on racing fuel. It has ben bored 30 over. Forged flat tops with the stock cast iron heads 68 cc combustion chambers. It pings like a bitch on pump gas. I figured compression is about 10.5 to 1. There is a OLD gas station on the south side of Fort Wayne that still sells 100+ octane fuel. You cant pump it your car. Have to pump it in a can.

We had a 1960 Pontiac station wagon "survivor" (24k miles) for a while... it pinged on pump gas, and I
would add a can of octane booster... ever tried that?

just for grins and giggles,, 1 qt of xylene to 1 gallon of gas will double the octane rating..or advance the timing to 32 degrees and open up the jets to double the size they are now and run pure methanol..
