Thanks for the responses. I had a look at the 'million dollar Cobra' thread, but it ran to around 80 pages and nothing relevant showed up on a search, but I get the idea.
So the clocking process trues up the scattershield alignment, and is an opportunity to check the flywheel for warpage (is yours aluminium, Dan?), and also the squareness of the gearbox mtg. face.
We then need to assume that the gearbox mounting holes on the scattershield are correctly positioned?
Never done this before with a purpose designed scattershield like a QT...so a further question:
Once the QT scattershield is dialled-in and screws torqued up, I should leave it fitted, and then fit the gearbox (Toploader) to the scattershield once the engine (with QT) is installed?

Cheers,
Glen
