Firing order for the Shadow Cars is covered in Workshop Manual Chapter A - Contents & General Information for both the original Shadow series (TSD2476) and the two-series (TSD4200). The entire set of technical manuals for these cars, and many others, are available for free download from the RROC-Australia Post-War Technical Library.

The car you ask about is covered specifically in this section: The SY Series: Silver Shadow, Bentley T-Series & Derivatives (1965-1980).

For the Shadow One cars look on PDF page 7 for specifics on the ignition system, including firing order. These cars are timed on the A1 cylinder. If you think things are horribly out of whack you need to get the A1 cylinder to TDC on the compression stroke then see where the rotor arm is pointing relative to the distributor cap. You'd then have to make sure the A1 lead is put on for the position where the rotor is pointing and then work your way around the cap counterclockwise from there following the order specified in the documentation.

There were three different Lucas distributors used on the one-series cars depending on the chassis number. That's also documented on the above mentioned page.
