13. Why do they call it a crate engine? Because it comes in a crate! Of course, they could call it a great engine, because it felt as great as Christmas morning when we opened the big wooden box to find the shiny new LSA staring back at us. Though similar in design to the normal GM LS series engines you find in Chevy and GMC trucks, the supercharged LSA has a massive intake with integrated charge air cooler built in. This is like a small radiator that is built into the intake and cools the compressed air after it gets pushed through the supercharger.
