My car was Old English White with red interior. I went to (1976 XJ6) BRG & Biscuit. I considered Opalescent Dark Green but at the time wanted to use Spies Hecker paint & matching metallics could be an issue back in those days should touch up ever have been required.

In today's world with the Glasurit system (as an example) being so good I would probably go ODG & Biscuit in water based, base coat & low VOC nano ceramic clear. You can spot repair metallics perfectly & no one would know you had touched it. Don't even have to paint whole panels.

 

Glyn, Thank you. That's very helpful info about paint systems. I am very tempted by opalescent silver blue or grey. I prefer not to keep the green because of the car park incidents...

 

Whether one likes or dislikes Ian Callum's CMC modded Mk2 (I like it) I think his colour choice is a knockout! (very similar to Opalescent Silver Grey if not OSG). BTW the reason I went for Spies Hecker paint is it does not react & bubble on lead (Pb) wiped seams ~ many 2K type products do ~ especially the isocyanate curing variety. It is also extremely durable & stable (25yr Warranty). The Glasurit system is benign when it comes to lead filling.

 

Gosh that car looks FAST!! There was a legal case in Sydney last week as to whether a particular number plate was acceptable after a member of the public took offence. It was on a Lamborghini owned by a Barrister and was "LGOPNR". I reckon that number plate belongs on the Callum CMC Mk 2.

 

4.3 litre XK engine tuned for high torque:

 

The reports I have read on this Mk2 by McCallum state "There’s a modified 4.3-litre XK V8" under the bonnet but the top of this engine clearly looks like the straight six XK.
What is the actual engine used here? I cannot see the top of the plugs but I cannot see the HT leads either so he has either rerouted them to come in the back of this is a very well made false cover over the V8 to make it look like an old XK engine. With a V8 the intake would be on th etop of the engine which again clearly is not as it has the SUs on the side.
Is this engine just a 4.2 bored out to 4.3 and still a straight six?

 

That is not a V8, you can just see the wires, looks like they're routed around the back.

 

IIRC it is a resleaved & balanced 3.8 XK with different cams & larger carbs via a 5 speed box. Not sure how they did that as the 4.2 has siamesed bores & a narrower centre main bearing. The metallic blue head also suggests 3.8 origins. Maybe used a version of the Eagle custom crankshaft. This was a very expensive car. Cost was not spared. Callum wanted a modernised more powerful XK engine but in the traditional fashion ~ no fuel injection etc.

You can just see the plug leads going to the rear of the engine. If I find a better pic I will post it.

 

Best I can do. Blown up from small pic in brochure:

 

I like the fact the HT leads go to the back of the engine presumably below the carbs before coming back down the engine in the valley to the front. Makes the top of the engine very clean and uncluttered. As the top of the engine on the XK is very pretty when polished up I might have to think about doing this myself. Just got to find 100 yards of HT lead.
