Are you converting to a full blown dry-sump?
The S54 does have a very good wet sump system. I've heard it called semi-dry, but that's a bit of an exaggeration. It does have a scavenge feature moving oil from the front of the pan to the rear, but that's a far cry from a dry sump system.

Benefits of a dry sump in reverse importance to me:
You can run more oil. (Not needed if you have a good cooler)
Eliminates oil starvation due to g forces. (Dual pan is fine)
Creates a vacuum in the crankcase freeing up power (10-15hp in an S54).
Gives you a flat oil pan allowing for flexibility in motor placement in the chassis.

The cons are the cost and the need for customization to make it all fit. I like to build and fabricate, and I need a winter project..
