he already must have the modified converter in the car though...am i wrong?...therefore changing the flexplate or welding on weights should solve all :)
It doesn't sound like it Doug because he said it vibrates real bad. The original converter pilot hub is smaller so it would fit right in the 360 crank. The problem is since there is slop there it'll tear stuff up.
BTW: Just wanted to clarify I didn't mean to be a smart axx by typing big. I just wanted to make sure it was seen.
