The only motor available in 69 for the GTO was the 400. The 455 didn't come out til 70. The only engine variations would be the base, Ram Air III, or Ram Air IV. It is most likely a base or RAIII. If it has the stock quadrajet it's not undersized. It just needs properly rebuilt and set up most likely. Look at the casting numbers on the cylinder heads and that will give you a good idea as to what you've got.
