Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly ...

Case Based Reasoning (CBR) is a novel paradigm that uses previous cases to solve new, unseen and different problems. However, redundant features may not only dramatically increase the case memory, but also make the case retrieval more time-consuming. Furthermore, camshaft grinding process is controlled by a number of process parameters, …

Variable Camshaft Timing is Chryslers terminology for variable valve timing. This allows the engine to advance or retard cam timing for optimal performance at all RPM's. The 5.7 HEMI cylinder head is also re-worked to improve flow. Intake manifolds receive an update, too. However, the 5.7 Eagle uses different manifold designs on different models.

A cam is a bump on a circle. When the lifter is riding on the circle, it's at zero lift. as the cam rotates, the lifter sides over the bump. Regrinding a cam is making the circle smaller, in order to make the bump bigger so it can be reshaped. David. four-thirteen, Dec 1, 2004.

Standard length is 6.775" for Intake and 8.075" for exhaust. You can vary up to .050" in pushrod length depending on which camshaft core the cam manufacturer uses! This is NOT information that any camshaft manufacturer includes with their camshafts, so it is always best to verify the length you need to avoid any valvetrain issues.
