Joe,
the ratio is 1.4 as far as  know.
The nominal original cam lift is 6.68mm so the valve lift is 9.35mm.
>From Denis Welch, the DWR8 Fast  road camshaft (268 deg) gives respectively 
7.44mm and 10.18mm, and the DWR2  Racing Rally (300 deg) gives  8.01mm and 
10.97mm. 
These  two require a pocket to be machined in the block.
I  personnaly use the DWR2 with single springs.
