Patella,
Basically what I'm getting at is people try to copy Dennis' work (atleast what they can see). Then they "produce" an inferior engine based on only half of what needs to be done. Then to top it off, they sell it for the same price you can get an engine from a TRUE modifier. Now you have high priced paper weights. They may run better than a stock engine, but they are not what people are expecting when they buy it. This only hurts the market, and the racers, in the long run.
I'm not saying all of the new builders are doing this, but some are, and many have in the past.
