hi shawn been thinking I played your video a few times and I don't remember my buddys jeep sounding like that and maybe somebody has put an even fire dist in here or maybe the had the dist out and put it back in out of faze at any rate the cyl. firing spacing is not evenly spaced on that eng. so either way that makes 3 cyl. in time and 3 that are out of time that's my thought I may be wrong I have been before any way it's worth checking out btw. as dave said the only manes that I can think of is Kenny bell who I don't know and lt'l john buttera and was at his shop a few times with a friend but I really didn't know him he has passed on now hope this helps....ted
