Engine number - 409

#1 · 16 December 2020, 17:25

I've got a 409 that doesn't have the original engine and I'm trying to identify where the replacement came from.

The picture is of the valve cover which suggests a Polyspherical 318 engine

The funny thing is that the number is only about 250 further on from the original, so I'm wondering if a later engine was fitted at Bristol cars.

Is the stamped in number on the RH side of the engine block (at the front, just below the cylinder head) a Bristol number or a GM number?
Does anyone else have a number that's something like 1641 - 111***C?
The polyspherical 318 is distinctive because of the "scalloped" valve covers ........... does anyone else have one of these?
