I've searched and found numerous threads of the debate about nitrous with big cams. I need to really know if the theory that applies to boost is the same for spray. I wanna gets cams and I'm deciding between N/A stage I or II's or special high lift short duration cams (turbo cams). I realize overlap can be played with using cam gears, but I need a definitive answer so I know if duration weakens the shot by letting it all 'slip' out the exhaust valve. TIA
