What engine is best for an LS swap? In short, the best engine for your LS or Vortec swap is the one you can afford. Sure, we would all love a shiny new LS3 crate engine from Chevrolet Performance or a rebuilt 5.3L long-block from Summit Racing, but once we crunch the numbers that’s not always possible.
How much horsepower can you get out of a LS engine?
Even in emissions-legal trim, a blown LS1 will pump out over 500 wheel horsepower, with 800 wheel hp available for a serious stroker effort. With turbo motors, the sky is the limit, as 1,000 hp is a common occurrence, with the ability to adjust the power output by turning a simple boost knob.
How much does a junkyard LS motor cost?
Getting all the parts for a real strong performing motor from the junkyard can be done, and the complete project can be assembled at a cost between $2,000 to $2,500, but it’s going to take a sharp do it yourself guy that will put in the time.”
How much HP can you get out of a 6.0 LS?
If we were to run the 6.0L in stock trim, the resulting power output would be around 400 hp (on this dyno the way we test). If we apply 14.5 psi from our turbos to the stock 400hp engine, we might get 800 hp.
