I recently overheard an exchange taking place at a car show about whether or not you could make drum brakes into “power brakes.” “Aren’t drum brakes always manual and disc brakes always power?” the one fellow asked. “That’s right, it’s why they have disc brake conversion systems,” a second fellow chimed in. “Whoa – not
One aspect of tire sizing that is often confused is aspect ratio. The aspect ratio is a tire’s section height as compared to its section width. The aspect ratio is often referred to as the tire’s “series.” With that in mind a 50-series tire has a section height that is 50-percent of the section width.

The lobe separation angle of a camshaft is often determined by the engine’s purpose, its displacement and its compression ratio. A 350cu in oval track racing engine, for example, often runs on a narrow lobe separation angle of 106 degrees. In contrast, a smooth-running performance street engine might use a lobe separation angle of 112
1.) How do I select the right size of carburetor? Carburetor performance is largely based on the air-speed traveling through its venturis. If they are too big the air speed will be reduced, too small and vice-versa. Probably the best instruction on carburetor choice is found in the Demon Carburetor Selection guide. It is based
