PowerSource has the popular Chevy LS series engines for your Chevy, in stock and ready to ship!
Our high-quality Chevy Remanufactured Engines exceed the original automaker’s specification – meaning they're actually better than new. Our LS series engines have been rebuilt from the ground up with new OE quality parts and updated engineering.
Our engine experts will personally match up the right replacement engine for your Chevy and guarantee the best price available.
We have full-line coverage of the LS engines from the standard 4.8 all the way up to the advanced technology of the DOD (displacement on demand) 5.3 , 6.0 and 6.2 models. We build our LS series engines complete with oil pan and timing cover and gaskets included to simplify installation. With 3 or 5 year warranties available, you're covered down the road too!
