Raffa...unless you go REALLY conservative on the timing and kill power, you're going to need better fuel. 14:1 needs at least 112 octane IMO. Add nitrous and you'll need more than that.
Like I said earlier, I'd be using VP C12 or C14 on motor only and at least VP C16 on the spray.
Hello Man ! yes .. from 10 years i use 100 octane for street use ( some time) and for race use with 350 spray.. i use 120 octane...im surprised by the old 496 with 12:1 when stop the engine was make lot of detonation with 100 octane... this 572 with 14:1 no detonation .. all time
