Galaxy (as in C-5A?),
We ended up buying a car that had a non stroked 351W in it but prior to buying it I was looking into a stroked 351. The combinations that everyone seemed to be voicing preferences for were 408 or 417. The warning I kept hearing with the 427 combo was the piston pin is very high in the piston and effects the area left for rings.
Oil control can be a problem. Roush is using a 402 combo with over 500 hp. You don't say where in California you're located but if you're at March, you're very close to Speed-O-Motive in Pomona.
