  1. Which LS Connecting Rod is Right for My Build: 6.098in vs 6.125in

    Which LS Connecting Rod is Right for My Build: 6.098in vs 6.125in

    Small changes offer big benefits when it comes to selecting aftermarket rods for your next Chevy LS engine build. Here’s a look at how rod length affects the performance and durability of an engine - and you thought you’d never use that Geometry you learned in high school!

    27 thousandths of an inch doesn’t sound like much. It’s about the thickness of a multi-layer steel head gasket typical for 4 cylinder applications. It’s almost exactly half as thick as a dime, which mics out at 0.053 inches. It’s a bit smaller than you might gap your plugs on an old-school points ignition small block Chevy. But like everything involved in high performance engine building, tiny fractions of an inch make significant differences in horsepower and durability, and that’s why rods that are ever so slightly longer than “factory stock” have become a big deal in LS engine builds.

  2. Stroker Science: Piston Speed, Rod Angle, and Increased Displacement Explained.

    K1 Crankshaft Stroke

    An intense look at crankshaft stroke and its affect on mean piston speed, inertia, and controlling the massive, destructive forces at work inside an engine.

    Engine builders have long calculated the mean piston speed of their engines to help identify a possible power loss and risky RPM limits. This math exercise has been especially important when increasing total displacement with a stroker crankshaft, because the mean piston speed will increase when compared to the standard stroke running at the same RPM.

    But what if there was another engine dynamic that could give builders a better insight into the durability of the reciprocating assembly?

    The video above shows two engines, one with a short stroke crankshaft, and
