It may sound odd, but I'm planning on the CS6490 springs used for deep pockets on my 73 with shallow pockets. They have a taller free height and actually a softer rate, but since they will start out compressed more in the shallow pocket, they should give a good ride while maintaining a good ride height. I think they were $60 from Advance Auto and available next day.
I also have the complete TRW/Moog spring reference chart in the suspension section. I scoured it, and did A LOT of calculations, and I still think this is the best soft front theory for a strip/street setup.
