COMP Cams Back To Basics Video: LS Valve Train Stability

Memphis, TN – In the latest installment of the Back to Basics video series, host Richard Holdener demonstrates how an LS valve spring upgrade can help prevent valve float.

B2B-LSStabilityGM LS engines provide an easy and inexpensive way to make horsepower, but their weak link is in the area of factory valve springs. When it comes to installing boost, an aftermarket camshaft or roller rockers for more power in an LS engine, it is important to also upgrade valve springs to avoid valve train instability.

In this video, Holdener explains exactly what valve float is and how it can occur, then uses three demonstrations to illustrate how horsepower can be improved on the LS. First he obtains dyno numbers using stock rockers and springs, then upgrades to COMP Cams Ultra-Gold ARC Series Aluminum Roller Rocker Arms, and finally adds COMP Cams Beehive Valve Springs to the total package. The dyno numbers show improved horsepower after each pull.
