In my opinion the Dart, with it's glass fibre body, spoilt a lovely engine. The V8 was a beautifully smooth and quiet unit that found a much better home in the Daimler saloon. I love those cars.
Incidentally, when Norman Dewis tested a Dart the chassis flexed so much that at 90 mph the doors came open!  |

I'm surprised that the chromium plating on the overriders appears to have been applied to a different quality or specification to the bumper.
Ie. It's lasted while the other hasnt. |

This is an early one! Anyone looking underneath would be forgiven for thinking they were dealing with a Triumph TR3 chassis.!
Does anyone know if there were any SP250s actually badged as "Dart" ?
I know the "Dart" name was dropped when Chrysler threatened legal action because their Dodge division owned the rights to it. |

Perhaps they are brass? Chrome should last better than on steel. |

I wonder if you know why the Daimler V8 was dropped by Jaguar? It is an interesting tale. In 2017 I was staying with the Heynes family (he who invented the XK engine) and over dinner one night Jonathan recounted the tale.
Jonathan received a call from his father to go to his office, and on arriving was told to take a Daimler MK2 manual out and drive it from Coventry to their farm near Stratford. In second gear. The engine survived and he was then instructed to repeat the exercise. In first gear. The engine finally waved the white flag and expired, which gave Bill Heynes the ammunition to declare the engine unreliable and to drop it entirely. Hence the demise of the Daimler MK2 and "proof" that the XK was far better. |

No I have not come across that story. It doesn't surprise me. If I were to criticise the Daimler V8 for anything it is the use of aluminium for the cylinder heads. I don't know if people simply neglected to use anti freeze but the one I worked on was in a terrible mess with corroded water passage ways. Perhaps the aluminium heads gave that engine the edge?
Apart from the 2.5 litre, sour grapes in Jaguar also extended to the 4.5 litre (Majestic Major) version which when tested in a MKX proved more powerful than the bigger Jag engine.
(Incidentally, talking about the MK10 I read where someone had fitted a V12 to good effect.) |

| All XK engines had alloy heads. the story of the MK X is true, but possibly not as you may have thought. When Jaguar were building the XJ13 they were using a new 5.0 litre V12 quad cam for the power plant. To test the engine, they put one in a MK X, and when Dennis Jenkinson was at the factory they asked him to try the car out - but on the condition he did not open the bonnet. He got one hell of a surprise! |
