Flexplates do not have a horsepower rating !!!
There was a 'design' change during the 99-00 ? years. Prior to that,the flexplate had the large round holes,the change introduced 'peanut shaped' holes and that design has been a failure. The later design when they fail were replaced by the earlier design and GM stock is zero and no longer available.

TCI all the way if your budget can afford it. Piece of mind can be priceless sometimes.
