Hi from London

Hi
As the title says I'm from London and have just got a 47cm wsm.
Had a little burn on it yesterday morning to see how it behaves and learnt a bit so tomorrow a whole 1.8kg chicken and a small 2lb pork shoulder, could anyone give me an idea on cooking times for these two bits, I was thinking around 4hrs at 225f
Thanks ,
