Drives good - and only just noticed, more power than the 285!
As per your suggestion it's at eight tenths rather than every last possible bit of performance.
Back to squeak - window is the channel worn out and creak chasing starts in earnest on Friday.
My money is on ball joint as the addition of weight changes the angles but we shall see.
Wife suggested this was sad indication of my lack of friends as if I was driving around with some mates it'd never creak - as it is I'm mostly solo!

Nice results on the dyno. Its a good job a fellow's got a sense of humor Ouch!! Had to laugh as the comment would have been just as appropriate for me! Nearly as jaw dropping as "its only a car"!!

A sense of humour is essential, you can't be crabby. (Groan)

Thanks - she also subscribes to "well it's nearly 50 years old - what do you expect - it's never going to completely silent" school of thought. Which is fine up to a point - but am determined to sort that creak in case it's safety related.
Have turned attention to rear brakes - one drum is egg shaped. Tony Wood to the rescue and at a very reasonable price including postage - amazing since they weigh a ton!. It's been iffy forever and just gets through the MOT. Hopefully now it'll be 100%. looked at lightweight ones but at circa £300 each thought enough's enough.
Will update next week after more fettling!

Comparing Andrew's dyno readings with the published data for the Mk1 1800 (Motor 1964) clearly illustrates how the early mild Mk1 cam provided good torque from 1000 rpm up to around 4500 rpm (18-80mph top gear) and then tailed off. This was ideal for the 1960s and made for relaxing driving with few gear changes. There was a later cam fitted to Mk11 /111 cars but I do not have the power /torque data but it did shift the power up the curve (ie less low down more at higher rpm) by a small amount.
The "270" cam as set up with twin carbs betters the early Mk1 cam before 2500 rpm and then the torque is quite flat all the way to 5000 rpm, imho an excellent range. Maximum power is almost 15% better.
(Note the quoted figures have been read from graphs, in the case of the MK1 1800 quite low definition).

For those that are interested - the pursuit continues.
New top and bottom ball joints, track rod ends - squeak still there but steering lovely!
Also - exhaust bobbins looked saggy so called into the people who supplied and fitted the exhaust and asked if they had some new ones - they took one look and said no (!) and said they probably just hung the exhaust on what was there - brilliant.
Now on mini bobbins with a little bracket and the whole thing is much nicer/less boom/vibration - a few quid and 15 mins made a huge difference.
Same story really with track rod ends/ball joints - they were ok - weren't unsafe/wouldn't fail an MOT but replacing them has transformed the car for the better.
In similar vein am lining up a list of small jobs - fuel pump is going to the rear where it belongs at some point, window channel is going to Mk 3 spec (rubber) when I can find someone to take on the fiddly job and shimming the engine mounts so they will line up properly - the rear one under the servo is irritating me. Because of the manifold I've got it won't fit on the left hand side of the mount (if that makes sense) so it'd been put on the right and just buzzed up with a windy gun so it's trying to pull itself apart.
They're all minor things but the lack of attention to detail by the various professionals is - how shall I put it - disappointing - but sadly no huge surprise!
Anyway - today we're converting to solid driveshafts. One of the spiders looked ok from the outside but on removal was pretty nasty - we may have found the squeaky culprit.
Will report further on the solid driving experience (!) once wheels are back on.
Also - keen readers will remember I added mini shocks to the front some years ago now - that and the rear anti roll bar are probably the two mods that improved the car the most IMHO - without detracting at all from it's comfort. I stuck on pair of el cheapo ones (£15 the pair) at the time and three years later they have passed their best. Have upgraded to some super dooper gas ones that were on offer - again will see if any difference!
More later......
Just been for drive and good news is solid driveshafts seem an excellent upgrade - no noticeable increase in harshness - bad news is squeak still there!
Out with the welding torch next I think!
Cheers
Andrew

I am aware of the whereabouts of a brand new shell when you're ready, Andrew. I'm beginning to think it's the only part you haven't changed!  Chris. |

Spooky - I said the same yesterday - you never know!
Car's starting to feel like that classic scene from Only Fools & Horses where Trigger claims that he's had his road sweeper's broom for 20 years. But then he adds that the broom has had 17 new heads and 14 new handles!

At least you now know a lot more what isn't causing the squeak!
I regularly watch and read reviews of some high quality vehicles including BMWs and Porsche and the trend seems to be to dismiss the fact that the steering progressively lacks feel and feedback as each new year's models emerge.
While I appreciate improvements to suspension design, wheels and tyres mean better grip one of the things I really enjoyed with the crab was the positive steering at speed that enabled corrections to be made before the car moved out of line. Trying to explain this to my US friends here who have never driven a car with manual rack and pinion steeing is fruitless and maybe the same is true of todays auto journalists. Their loss!

Back on the window rattle today.
Replaced all four windows with rubber surround stuff - as per Mark 3's I believe.
Rattle still there in rear passenger door and now passenger front door has a murmur!!
Driving a rubber door stop between glass and frame stops rattle on rear one.
Can find nothing loose within door - all rods isolated - any ideas?
Ref the creak from front - bottom arms done both sides, tie bars checked, new bushes but no better in fact getting worse as all suspension now working properly which leads me to hope it's the top arm which is being done Friday.
Also any ideas where to re-site fuel pump...was thinking in the spare wheel tray - nicely protected, clean and dry and carry spare in boot - not that I have one for the minilites anyway!

I have my electric fuel pump mounted on some small rubber exhaust bobbins mounted to the underside of the boot floor.

I have put an electronic pump on the firewall in the engine compartment.  |

Window rattle sort or resolved - took me a while but reversing some of the modifications (!) made - by me and others to originally eliminate the rattle seems to allow the new channel to do it's job.
There's a tiny noise on occasions from the door handle mechanism - which stops when exterior button pressed down but otherwise all silent. I'm going to live with it - it is pretty insignificant.
Re the fuel pump - it's on the bulkhead at the moment but it's loud ticking irritates and (it's a Facet) it's supposed to be a push, rather than suck thing really (!).
Will put it on the to do list for the Autumn I think.
Back to the creak tomorrow.
First proper outing Sunday week - fun/light-hearted navigational rally with full compliment of passengers so want it right for then - if only to spare me the constant ribbing!
Although with all that weight on board it will probably be silent!

Silence is golden!
Top arm inner bush the culprit.
