Nitrous inevitably breaks things & /or so hard on parts that they just don't last, but'll last longer if built solely for nitrous.
My buddy runs 11.2 w/closed chambers & solid roller in his 451 and tuned it to run on 87 octane, and it's damn fast in that road runner.
You'd be surprised how comp you can get away with on the perma torques.
However if someone gets stupid with the timing, they'll pop.
It's all about knowing.
