1969 Dart Street/Strip (Re)Build

The day I've been waiting for for a long time. Engine builder dropped by and we fired the car up for the first time. It started right off the bat and ran excellent. I will have to say that it's a bit louder than I thought it would be but that's not a problem at all. Trying to process a video now and upload it. The audio doesn't do it justice but you'll get the idea. I'm just happy it runs. Only problem we had was that we found out the powermaster alternator was dead. It wasn't charging at all. So I'll have to pull that off and get it fixed. Other than that things look good this far. I'm having issues with my brake lines wanting to leak on me though. I thought i had then tight but I got some brake line wrenches and tightened more. The leak slowed but still there. Any thoughts on that?
