Welcome once again to Thursday. It’s that time of the week when we take a look back in the Chevy Hardcore vault, and locate an article that you guys might have either forgotten about, or might not even know exists. Either way, we think you will surely enjoy this editorial flashback.
Last week, we looked back at the proper way to set valves on an engine – be they solid or hydraulic. So, I thought this week, we should take a look back at a little rocker arm explanation by looking at Valvetrain 101: Rocker Arms. Let’s face it, you can’t adjust valves without having a little knowledge about the rocker arms.
It was way back in 2010 when we compared shaft-mount to stud-mount rockers and talked to the experts at Comp Cams, Harland Sharp, and Scorpion so you can help make an educated decision about what’s best for your engine
For instance, there are different things to consider when it comes to choosing the right rocker arm. There is even some math involved, so hopefully, you paid attention in school. In the Throwback article we explain how you first need to decide what rocker arm ratio that you are going to use on your engine.
This is important, because it can affect the camshaft’s lift characteristics. The author gets into some math explaining it, but you’ll have to check it out in the original article. Finally, the author dives into the decision of shaft-mounted or stud mounted rocker arms. This is to help you decide which is best.
So, if you’re doing your due diligence in choosing a rocker arm system for your latest engine build, check out Valvetrain 101: Rocker Arms. You might just save yourself some time and money by avoiding a costly mistake.
