I'm looking into changing the engine in my van, although i haven't decided what to yet it will be a ford lump. One major factor in my decisions though is how it will affect my insurance?
I know you see a lot of adverts on ebay that go like 'only dwn on logbuk az 1.2 so rate cheap on inshorance innit' but I fancy doing it the legal way

I assume lots of people have done this? How much trouble did it cause?

Cheers
