That's ok, nitrous is not for everybody. I used to run a nitrous motor that I built specifically for nitrous...that was 8 years of nitrous from one end of the 1/4 mile to the other. It can be a very reliable power source with proper tuning, it just gets really expensive to run on a regular basis. The initial investment is not that much, but to run it right (and run it often) takes quite a bit of $$$$....Needles to say, I run NA now with my stroker.
So are you saying you don't like anything that is turbocharged, supercharged, nitrous injected; or runs on methanol, ethanol, e85, nitromethane, oxygenated race fuel, etc???....that doesn't leave very much stuff to watch race.
To the OP, yes, a properly tuned Holley dp carb would be well worth a try, and will probably out due both of your other carbs.
