Low compression is normal for svt from what I'm told, due to the VCT.

Thanks for the input Matt. I had another look at the cams and there's no way that the bar will go in with the cams the other way round. I turned the engine round until it hit the pin and the bar slipped in very easily so I'm thinking this is right.
So the timing is right and I've changed the plugs and wires.
I don't know what to try next.
