Sorry for not replying sooner.
The Limit was a Discoteque in Middleton, not far from Blakeley, Thursday nights were popular as they didn't charge girls any entry fee.
Then again, Cornwall was fun in those days too.
Happy days...

IIRC I used the IRF540 in a battery power supply, because of the low forward volt-drop, but the current was less than 150mA. Perhaps put two in parallel to improve reliability? Diode clipping for back-emf is usually a good idea; If you can put an A-D input to read the pot then you can confirm things...

Sounds like you need to visit your local "Noggin" and let a few other members have a look under the bonnet.

Excellent...
Reminds me, someone once said...
When the only tool in the box is a hammer, everything looks like a nail.

That is sooo ooo nice.

Yes, Motorcraft was originally specified, but the table of Ignition Advance settings I have only covers Lucas distributors - I thought the info might be useful, but not as useful as the graph you supplied!!

I wish the Sabre Six Manual had this level of detail, you lucky thing!

Peter, Is there any sign of corrosion on the broken surfaces showing it developed progressively, or does it look like the break happened "instantaneously"? Did you hit any big potholes recently, or can you suggest anything that might have led to this? AFAIK this is the first time ever I've heard of ...

IIRC one question you asked earlier was about electronic ignition. An acquaintance has an AC Ace with the straight six engine, same as mine, and he's running a Boyer Bransden system as this keeps the points (for originality) but acts as a current booster, so the current through the points is kept ve...

Don't know if this helps, but according to Marcel Chichak's TDC Engineering chart of Lucas Distributors, the 31D6 dizzy on the 3-litre Scimitar engine was set as follows: 0-300 rpm 0 deg Advance 300-550 rpm 1.5 deg Advance 550-1500 rpm 9 deg Advance 1500-3000 rpm 13 deg advance These figures are in ...

NPTF = National Pipe TAPER Fuel,

Bit pedantic, but isn't it Pipe Thread Fine?

I don't think their computer data can be right so IMO use the data provided above and get them to ignore what the computer says. Car weights, chassis and wheel dimensions and steering geometry have all changed for different models over the years. No way can "one size fits all" apply.

Just a suggestion -
I bought a low-cost fuel pressure gauge from Demon Tweeks which showed my pump was giving 3 psi - but do you feel confident enough to break into the fuel pipe to measure this?
I'm sure you know, messing with petrol in a glassfibre car can have dire consequences.
