Yes, when Vauxhall were designing the engine, it turned out to be very efficient, and was pumping out around 150bhp stock. Vauxhall realised that this would overshadow their precious 20XE engine (Red-Top) and decided to stick a very complicated inlet manifold on, to restrict power. Much gains can be made by changing to an aftermarket manifold from Velos,Lexmaul or Mantzel.
