I don't disagree, BUT... It depends on what you're end goal is. For a guy running a tune, 3.4" pulley and headers, a 300m and 7/8" chain is unnecessary. A lot of the techniques used in a "built" transmission translate to a great "standard" build. A good build using stock parts will result in a quicker shifting, cooler running, longer lasting unit. It just wont handle the higher horsepower levels. Think about a taxi, or soccer mom's minivan. Not race cars by any means, but they live in some of the harshest conditions.
