had one neighbor down the street drive his dragster up and down the street to get some time on the new motor, must of had a few new motor's a couple years ago, neighbor behind me has a low 9. super-pro Ford ranger, so no problem with any of mine,,I do go next door and warn the 86 year old fellow that lives there when I get ready to start mine up, don't want to startle him too bad, but he does say he likes the sound of it.
