There were many configurations of the 429/460 motors. The blocks were all very stout and some models were premium blocks like the DOVE-A and DIVE-AA series blocks. The 429 and 460 are the same block, just a different rotating assymbly. The many different cylinder heads played a big role in the motors performance, and thats where you need to watch mostly are the heads you get. You go through the motor and build it right and put a good series head on it, that 455 should be no problem. (sorry Olds guys). Here are a couple sites to muddle through with some good reading and casting numbers.
