Building a hot rod or a race car is certainly a time-consuming labor of love; finding a donor car, sourcing all of the hardware and trim, and putting together a driveline that works for its intended purpose. When it comes to the engine, it can be a tedious affair and there are seemingly limitless directions you can go.
More than ever, we’re seeing enthusiasts turn to crate engines from our friends in the aftermarket. There are OEM-type replacement crate engines out there, but if you’re really trying to stand out that may not be a perfect solution, either. Of course you can modify your crate engine, but more often than not it could effect the warranty.
So what do you do? Take a look at what is available for our friends at Pace Performance. In recent weeks, they’ve announced a 570hp crate engine that’s based on an LS3 — but provides an additional 140 horsepower — with a touch of personality and exclusivity.
