I thought some of you would enjoy reading this article ( while your other half is out shopping or your sitting in the middle of the mall waiting). This article is about the importance of matching the right components and where focusing on the heads, carbs can make a big difference along with the cam matching what your final goal is. It's more technical in explaining port design but never less very interesting. One thing to keep in mind is that this article is about making your engine perform better, but one needs to provide enough air flow to achieve that. That is always a good topic on this forum. Enjoy!
