425 and 455 are the same block. The reciprocating assemblies are fully interchangeable.
Pin placement in the Pontiac piston is slightly different, but it doesn't seem to be a problem with "street" engines.
Here is an example.
The only one I've been involved with, used 425 rods and 4.125" Arias pistons.
