I am looking for some information (preferably pictures if possible) 
of the engine bay of a Mantula V8.  I am in the process of fitting 
the Rover V8 into a Martina ( similar body/chassis ) and it would be 
very helpfull to have photos of engine bay layout.  Also if anybody 
could tell me at what height the rocker covers sit above the top 
chassis leg, I can get the engine mounted at the correct height.

Any help would be much appreciated.
Thanks
Andy.
