Dating TC engine/ translating engine number

Been meaning to do this for a while...
Bought a TC engine for the estate about 18 months back, and I was wondering what age roughly it was. Anyone any ideas? It's original car is long gone- it was extracted from a rotten car for a kit car project that never happened.
The engine number is 18V E-180850
Be interesting to compare to what other folks have & see if we can vaguely date it. I suspect it's relatively early, as it had an inertia- type starter, but I've no idea when that changed.

OK anorak time, your engine number is actually
18V 408E - H180850
18V = 1800cc Verticle (in line)
408 =
Lucas 16ACR or 17ACR alternator with negative earth
Mechanical fuel pump
Pre-engaged starter motor!!!!!
Centre change gearbox
E = Carb crankcase ventilation
H = High compression
Engine numbers started at 101
I can't tell when the starter motor was switched over.

No comment
Cheers Chris, that's great
Quite surprised there's nothing to denote it as a twin carb motor... or was it not originally?
Interesting on the starter motor

dont take anything for granted on a 40yr old engine...

There is a twin carb indicator in the chassis number. TCs have a "T" in the code .

Ahh. Wondered if the engine would have one too...
Chassis number is another matter entirely... Is body type (Coupe/ saloon) covered in the chassis number? Guess it must be.
Would still be interested in where other folks' TC engine numbers are relative to this one, so I can get a very rough date (don't want to know your actual numbers, just "mine is about 2000 less and is 1974" would be ace

).

4 = 4 doors (Saloon)
2 = 2 doors (Coupe)

The 408E part engine number suggests a single carb engine.
Twin carbs should have a C, F, T, W, X, Y, Z as part of the engine code.

That makes a bit more sense, I thought that there should be an identifier in there somewhere. Doesn't bother me either way, it's got the right carbs & manifold at least (and is a high comp, big valve head engine)- just interesting.

Going for anorak Gold star now. If you come across an engine with codes 641E or 642E then you've got a Police spec engine.

You are a very useful person to know Chris, but you do need to get out more

Can't really tell as none of the engine internals seem to be different, however two other items do. A rear mounted oil filter (not sure what that means) and a heavy duty clutch pack.
