    No, the General Motors LS V8 Engine Series is NOT a Copy of the Ford Windsor V8

    The Chevy vs Ford debate goes back decades. It continues today just as it did during the Golden Age of muscle cars, covering everything from trucks and cars to engines and transmissions. This long-standing rivalry has inspired memes, window stickers, and countless comedy routines. In fact, some even have proclaimed that the LS V8 engine is just a copy of the Windsor.

  2. Gain 17 Horsepower for Under $100 With I-M Shield!

    Who doesn't want an extra nearly 20 horsepower, and 10 extra pound-feet of torque? And what if that extra power cost less than $100, and could be installed in under an hour? Well, say hello to your new best friend: Heatshield Products I-M Shield™!

    I-M Shield simply attaches to the underside of the intake manifold via its specially formulated adhesive backing that can withstand temps to a sustained 300 degrees Fahrenheit. I-M Shield creates a thermal barrier between the intake manifold and the top of the engine, minimizing heat to the intake manifold. Even modern composite intakes are susceptible to heat soak, and the heat can raise the air temps inside the intake, costing horsepower and torque. By keeping intake air temps cooler, the computer is less prone to reducing ignition timing and/or increasing the air/fuel ratio, which decreases horsepower, torque and throttle response.

    On any modern electronic fuel injection engine, when air intake temperatures r
