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

My 9.4 compression (stock) 340 would detonate 1000 foot out. with 91 Premium. But only in the heat of the summer. one gal of 110 to 10 gal 91 would fix the problem.

If i understood then, what i do now, i would have cut a hole in the hood and seal it to the carb instead of adding High Octane Fuel.

There is many many variables as to why you should or should not run pump fuel. and "X" amount of compression is not the answer either.
