Hi Adam, it sounds like you and I have a similar back-story with our 7s! Thanks for reading the blog, although I am ashamed to say I haven't updated it for ages. In my defence, I have been out of the country quite a bit but will certainly get back on it.
The engine is ready to go in right now (well, not literally), as it is re-built and waiting. I hope to God it runs, though. My biggest fear is putting it back in to find that I did something incorrectly in the rebuild. Once the engine and 'box are back in, the car is finished. Pretty much. Just the minor (!) jobs of fitting the front screen and finding/fitting the prop. Oh, then putting the stickers on and washing it.
Thanks for the hints on refitting, very useful. Do you think it is best to fit all components to the engine off the car, or in situ? I am thinking manifold, carbs, starter etc.
BTW, I took the plunge and used short self-tappers to refit the gearbox heat/sound board and it went fine.
All the best (and I promise to update the blog soon)
