Phantom 3 engine

What wonderful complexity!

Part of the Phantom 3 engine laid out ready for assembly

The Phantom 3 was the last of the 'large horse-power' cars built before the War. This was the last of the line of engines that followed the Silver Ghost. Although the capacity of 7,3440cc was similar to the preceding Phantom 2 it was a V12 rather than a straight 6. In effect it consisted of two 3 1/2litre cylinder blocks mounted side-by-side on a common crankcase.

We undertook a 'short engine' overhaul of this unit, converting the connecting rods to accept modern thin-wall shell bearings.
