Robert Lilley on this list a few years ago went through his WBX'er and Lilleyfied it to boost smoothness and performance. I don't remember all the details but part of the goal was to refine many of the systems, like porting and polishing, different kind of lifters. specials cam, polished oil pump ports, water pump, etc. He basically did a lot to reduce internal friction that robs horsepower - as well as increase HP output. Don't remember if he used a big bore kit or not. Not sure that is what he was after. I seem to remember that he anticipated a 15 to 30 hp increase but I'm not certain about that. Dunno what happened to him or the project.
