The time and money that goes into development for our Mountain Motor Pro Stock stuff is crazy, but the 500" stuff is 10 times worse. Over there it is more about racing check books than anything else. When you enter into the world of Pro Stock you find that secrets are like gold, and covering your best information is key. We spend crazy amounts of effort to find something that will give us another 5 hp, when most other forms of racing are looking for another 100+ at a time! Honestly the part that most people don't know about is the upkeep. Granted, to build a new competitive Mountain Motor is about 125k, if you plan to run competitively you have to figured after about 25 runs it needs new rods, rings, bearings, etc...

Don't even get me started on what kind of money there is when you start testing different intakes, carbs, spacers, headers, etc... because what works on the dyno, doesn't always work on the track!
