video time check this out !!
this was my car also it's a rare 65 dart charger 273 commando with cam and d4b intake/ headers. don't know anything about the cam but that engine would rev to the moon.. previous owner use to race it. here is a video .. It's tired as you can see and real loose. those revs were over 6k one 6500 rpms. this video is right after I installed new valve seals.. did not help much..
