I experimented with the kerosene mixture 20yrs ago in a 1970 Mach-1 Mustang with a freshly blue-printed 351C-4V. I had a hard time running it on regular gas (premium was OK, but costly). I started with small amounts of kerosene per gal of gas and worked my way up to a "half and half" mixture. The pinging never stopped (unless I really retarded the ignition timing) and the engine seemed to have less power as I increased the amount of kerosene. Eventhough kerosene does burn slower, it did not help in my case (maybe it's just an old-timer's myth).
