I read the same, i believe LPG burns at a higher temp. That said my engine has never overheated (at least the dial has never gone above centre), but still had gaskets blow out.

On a side note also whats everyone's general take on these running on LPG, I know it runs hotter on gas so is this a contributer to HG failure,mines on gas

LPG mechanic who fixed my system said they only run 3/4 degrees hotter on LPG than petrol.

What so my new p38 heads wont go straight onto the 3.9 disco block

The camshaft has nothing to do with the heads - it sits at the top of the block between them. These will just swap across.

If you are using a block from a 3.9 hotwire and keeping everything else from your range rover it will have to have a short-nose camshaft of the same type that is in your engine currently.

This is because the ignition and timing systems are completely different and the cam is critical in that process.

Yes the block is the same..the THOR engine used different external components and sensors...but the Engine internal (Block etc) is the same!

basically the same block bur 3.9 has the smaller crank bearings and machining for knock sensors and crank sensor
 
Yes that's what I had read, this guy with the 3.9 says its run on gas all its life its only got a 2 gallon petrol tank it was running fine when parked up
