Wondered if you were familiar with TunerPro? That is what I used to tune the 502. It a great program, extremely versatile. Its kind of free, although if one uses it, one should send Mark some money, as he's put a ton of work into it.
As I recall, some of the tunings for the 454 have issues on the earlier ECMs, so you may have some room to work with. The stock timing curve is fairly linear. That means one can add timing to the bottom end which really helps throttle response.
