I prefer stages though to progressives. They are just to finicky still for my taste.

My buddy runs a 150 wet shot progressive on stock bottom end and has been doing so for years, and still no problems. It's a lt1 but either way the progressive is the way to go for a bigger shot.

yes, limiting the low RPM torque is key to stock motors living a long life. Mine failed at 685rwtq @ about 3500rpm. My buddy and his turbos have set numerous records with just over 700hp, but he is still under 650rwtq tq, and you know how progressive the torque comes on with a turbo, peak is much later/lower than spray. I did a thread with a turbo vs a dual stage dyno sheet overy lay, and i was able to mimic the turbos power/torque curves almost pefectly. I too, prefer multi stage over progressive. However, with the better seat materials these days in the n2o noids i will be trying the progressive soon. Just make sure you get a progressor that can have different pulse rate per fuel/n2o solenoids as they can require different rates to be correct.
