I say go for it.
Like franklee says, just go out there and start wrenching on something.
At the worst you blow-up an old 400.
Current R&D is working on direct injection gasoline engines, diesels fed gasoline. Maybe that's backwards.
You mentioned a wye intake. How about warm up on gas, run on diesel setup?

I can't understand why my MPG's are so low..........
