Stock 340 dyno tests?

I agree that in the end of the day it mainly only matters how well your car performs.

The one thing I don't get with the track tells the true hp, is how can it ever be verified?
If dyno numbers can't be trusted then you have no way measuring the engines hp and verify the tracks calculated results.

To me IDC if mag & video result aren't exact, but it the numbers most of us know and use to compare mods with each other, if 400 dyno hp is only 350 track calculated hp the 400 hp has better usability cause I can compared to all the available info that expressed with those figures.
