Pace Performance Announces Primed and Prepped LS3 525HP Crate Engine Package

Our friends at Pace Performance have offered engine builders and hot-rodders crate engine packages for years. From the iconic ZZ350 and ZZ572, to various LS engines. Some, are direct replacements for production cars, while others, implement the solid foundation of what Chevrolet Performance provides with Pace Performance putting their own creative spin on it, using aftermarket hardware and technology.

We’ve seen this from them before, like with the 495hp Pro-Flo LS3, but they’ve recently accomplished assembling another winning package with the Primed and Prepped 525hp LS3. They’ve provided us with all off the details, specs and even product images below.
