I'm not knowledgeable enough to know all the ins and outs of the dyno sheets and the values on them as far as fuel consumption and minute details. I don't however believe the hp numbers are a reflection of the cam being too small. With a very similar w2 build and a smaller hydraulic roller cam I made 50 more hp and 60 more ft/lbs at lower rpms. This was also done on a dyno known to be conservative.
