I Cannot Turn The Engine

So I am doing my first valve adjustment/general service. The Kokeln intercooler is off and when trying to turn the engine by the fan nut the belt just slips and crankshaft is not moving. The nut on the crankshaft pulley does not move it - rock solid.
I also tried to move the engine by turning rear wheels in 5th gear (915 box) - nothing.

Is there any trick here? would removing spark plugs help?

The engine is modified = 3.4 Mahle P&Cs 7.5 compression, AASCO High Performance Valve job with springs and titanium retainers, SC cams etc. Does it make a difference?

Please help.
