Over the course of its 20-plus years of production, the trusty GM LS engine came from the factory in a wide range of displacements, from a humble 4.8L to a rowdy 7.0L. So if you’re thinking about an LS engine swap, LS engine build, or LS engine upgrade, the first number you’ll likely care about is the LS motor’s displacement in liters.

This handy LS resource page is a good one to bookmark if you’re considering an LS crate engine for a swap, or looking for a 6.2L (about 378 cubic inches) LS short block to start a project.

The 6.2L LS Engine Family

After being introduced as the L92/Vortec 6200 engine in GM’s large SUVs, the 6.2L’s ascension up the horsepower ladder got really interesting when the LS3 arrived on the scene as the base powerplant for the Corvette in 2008. Horsepower climbed even higher when GM decided to supercharge it to create the LSA for the new ZL1 Camaro, then again to create the LS9 for the new Corvette ZR1.

All told, if you need a good foundation for a mega-horsepower build, then the aluminum block 6.2L can probably handle it.

    I am thinking of swapping the original (high mileage) LS2 in my 2007 Vette (Mar 2007 build) for an LS3 (GM crate engine approximately 480-500hp), 6spd manual Z51 coupe. Just wondering what unforeseen probs I might encounter…ECM programming, clutch, etc. Have also replaced the rad with a Dewitt ‘Direct Replacement’ which also hooked to the stock oil & trans cooler and has much better cooling.
