Pro Stock engine efficiency

Several week's back, i thought about what timing a modern P/S engine ran? Well, I got my answer.......

Been watching NHRA Q2 qualifying all season on ESPN3, which by the way, is some of the best laid back racing coverage you'll ever see.....period!

Anyway, Bruno Massel was in the booth for a time, and Mike Dunn stated that Fuel cars run about 60* of timing, which is understandable considering the slow burn rate of nitro. He then asked Bruno, how much does a P/S car run? He replied that most guys never disclose their tuning numbers, but give or take.....20*. Wow, how sweet is that.
