Quote: If you do pull the tranny bolt the converter back up and check the runout with a dial indicator. I have a B&M flexplate on my 340 that I had to modify to work. Won't buy another one.
but the flex plate was workn before with no issue could it just go bad?
If the flexplate was in before this and was ok it would still be fine, there are no extra weights on it unless you put some extra holes in it for some strange reason.
