It used to be four months now it's two. 19th century it could take weeks or months to tally the vote. Other big big difference is in the US legislative and executive branches are separate and in Britain they are not. Your Prime minister is a member of parliament. US presidents often aren't members of either congress or the presidency. The system also tends to be centered around the idea of good faith which admittedly is a bit tattered.
