V8 popping and banging

Recommended Posts

Stripped down the top end of the P38 to change the inlet manifold for one that was on a LPG converted car. 

Today I started the car on Petrol for the first time and the engine was running rough. It seems to be miss firing as well as popping and banging generally rynning as rough as a bag of spanners. The whole top end and engine bay wiring loom was taken from a donor car that ran very well.  The inlet manifold was torque down evenly from the centre out. 

Where is my problem likely to be?

I'd check wiring first before delving into other stuff - everything connected as it should be, no wires or hoses hanging off etc.
