Everyone brags about peak horsepower, but the shape of your torque curve is what actually determines how your LS swap feels on the street. Two engines can share identical peak numbers and drive completely differently — here's why that gap matters more than the dyno sheet headline.
Your LS pulled a killer number on the dyno, but now it stumbles at highway on-ramps, surges at cruise, and acts like it hates you every time the temperature climbs past 90 degrees. The dyno didn't lie — it just didn't tell you the whole truth.
Walking into a salvage yard to buy an LS engine without a game plan is how you end up dragging home someone else's problem. Here's exactly what to look for, what to listen for, and what to walk away from when you're hunting junkyard gold.
Running a carburetor on an LS engine sounds like heresy to some builders and pure genius to others. Both camps have real arguments worth hearing. Whether you're building a weekend cruiser, a dedicated track car, or a daily driver, here's how to cut through the noise and pick the setup that actually fits your life.
Every parts catalog is full of bolt-on upgrades promising massive power gains for your LS build. But when you're driving on public roads, not staging at the track every weekend, the calculus on what's actually worth buying changes dramatically. We break down which LS bolt-ons deliver genuine bang for the buck — and which ones will have you spending serious money for gains you'll never actually feel.
Choosing the wrong transmission for your LS swap is one of the most expensive mistakes you can make — and one of the most common. From budget-friendly 4L60E rebuilds to modern 10-speeds and row-your-own conversions, here's how to match your gearbox to your goals before you pull the trigger.
Hot rod builders obsess over peak horsepower numbers like they're the final word on how a car performs — but experienced LS tuners will tell you the dyno sheet tells only part of the story. Variables like dyno type, atmospheric conditions, and tuner methodology can swing results by 30, 40, even 60 horsepower on the exact same engine. Here's what those numbers actually mean, and more importantly, what they don't.
You've got an LS engine and you want more power — but the path you take to get there matters more than most people realize. Superchargers, turbos, and nitrous each have real strengths and real drawbacks, and picking the wrong one for your situation is an expensive mistake. Here's the full breakdown to help you make the right call.
