360 engine vibration

Or get a B&M flex plate for a 360 if you don't have weights. Did you rotate the converter to see if there are any weights? The balancer looks like it's from the late 80's or early 90's 360. Is this a magnum or premagnum engine?


Do these B&M Flex plates come balanced for LA 360s? I am planning a fresh 727 and converter for my Duster 340 and would like more info on this option.
