Once upon a time, when crate engines first became a thing, everyone was thrilled to be able to get engines that made real power with a warranty. And when they started being tested by all the magazines, and in most cases made more power than they were rated for, they sold jillions of them. And for good reason, they were great options. But somewhere along the way other companies started building crate engines as well, and then everyone started building their own LS engines and three camps were formed.
The first camp are those who upgrade a junkyard LS for a project, the second is buying crate engines from an OE or aftermarket company, and the third is having custom engines built. But have people lost confidence in what an OE crate engine makes? Do you wonder if they are what they say they are?
In this latest video from Richard Holdener, he’s running a test with a GM Performance Parts LSX 427 Crate Engine to see if it makes its rated power or if it makes even more. Check it out below.
