Ignition timing problem

[madteg]

I have fitted a new engine to my 2.4 2004 liberty, but did not notice that the crank position sensor was in a different position. Anyway I have now fitted the trigger wheel to the front pulley as different to the new engine. I have mounted the cps so I can move it to set the ignition timing. Anyway my question is what should the ignition timing be degrees before top dead centre. I can not find it anywhere. Thanks.
