Anyone Here Ever Dyno Their Mild Built Small Block Car?

The only part that the dyno would have helped with is the change with the carbs. So you pull twice to establish a baseline, then replace the carb, then pull to tune, then pull two more times to establish the change. Comparing numbers between dynos is not accurate. So the next step for you is to get to a track, get an ET/MPH, then weigh the car as it was raced. Use the MPH as the power indicator because that's reality as basic as you can get.
