Welcome to Flyertalk, Bonzo_7 - it's good to have you here.
Now unless there's a typo in your post, or my maths is somehow off, that looks to me like you have 6h35m to transfer.
That is more than enough!
You will hopefully have your bags within 30mins after landing, almost certainly within an hour. You then simply stroll round to the Norwegian check-in desks and you'll be all set. [ETA: as noted above you may well have to wait a while until Norwegian checkin opens]
Even if you're several hours delayed, you should make it. The risk you have is if your flight is cancelled. Keep an eye on the weather if it looks like it might be a dodgy day, or if there's any sign of major disruption come back here to seek advice. To be prudent, check the night before if there are avios seats on other services to EDI in the morning, just in case you need to book a last minute rescue flight.
