I agree, Aaens books were not bad but there is so much better stuff on the net for free and more in depth. Take hold of your inner google after reading the tech pages. Something that helps when your reading about clutch theory, is have your clutches or sled handy so you can while reading about the forces involved, you can look at the cluthces and see just what they mean. one on the bench with the spring out is helpful as well, also, cut a junk out of a piece of belt so you can set it in the clutches to give you an idea of what the weights and rollers are doing at different points in the shift. Like front end geometry, it is alot to get your mind around and from time to time, you might need a refresher read.
Jetting is the same. If you have a set of carbs, good to have them in front of you to look at while reading about jetting.
Both of these subjects also require a bit of practice time to really keep it in the brain, testing on the lake with either jetting or clutching will really drive home what you read. Bolting on clutching parts just to see what they do will show you alot.
