A slant 4 engine, that's interesting. Only slant engines I knew of were the Chrysler 6s. Some people not in the know, thought because they were laying a little side ways the cylinder walls would wear out fast on the bottom side. Funny how people think. That engine turned out to be one of the best engines Chrysler ever made. Good luck with the car. It shouldn't be hard to sell when done. Unique color combo, nice, but unique. Are they Rostyle wheels?

Yes, they are Rostyles - and same bolt pattern and size as my midget though larger studs.
The engine was to have been part of a larger Vauxhall development of a diesel and a V8. Only the slant four came of it but the diesel connection means the block is immensely strong. Blydenstein Racing ( the "cooper" of Vauxhalls got 250 horse out of them) virtually the same engine is the Lotus 907. More info here.
https://en.wikipedia.org/wiki/Vauxhall_Slant-4_engine the 907 was also used in the Jensen Healey.
the colour is Tasmin Orange. The colours were all named after tracks: Monza Red, le Mans Blue, Elkhart Yellow, Monaco White, Sebring Silver Starmist and Goodwood Green. The orange is the rarest and in fact the keeper of the registry was adamant that there were no Tasmin Orange cars till the PO of mine found two here in Canada with original paint. (Mine was originally Monza Red) and, the stripes and bonnet colour were from the factory.
and, yes Opel = Vauxhall = Holden = GM same company and while not the same cars, there is a family resemblance - Torana in Australia too.
