Be fun to see some of the top secret info for the year NASCAR switched over, probably hundreds of thousands of dyno tests that should show a trend, maybe plot on a graph hp 5 years before and after the switch so you can see how much power was naturally increasing VS a blip for the year they switched. Of course NASCAR has to worry about fuel miledge as well and there is just no way a carb can match it, you can't cut fuel on a carb when coasting, braking, lean it out a little to try and make one last lap on your fuel...
