Mechanically similar, General Motors’ LS and LS-based Vortec engines wound up on almost every branch of the GM family tree: Chevy, Pontiac, GMC, Cadillac, Buick—heck, even Saab, Hummer, and Isuzu got some LS love.

Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era.

These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.

The aftermarket is strong, crate engines are available, and used motors are often cheaply sourced through junkyards.

Summit Racing has created a series of comprehensive guides for each engine in the LS family, so engine builders and tuners can have a handy reference for their projects.

This specific guide is for the GM L96 6.0L engine.

You can find more LS engine spec guides and LS-related information here.

    I have this engine in my 2500hd 4×4. And I love it. Even stock it is a hoss.

    I did a l96 swap in my 58 apache.I switched to a Holley intake and 750 double pumper carb. I am also running a toploader 3 speed behind it. Everything is stock in the engine but im wanting to do a cam swap. Can you suggest a good street/strip cam for my application?

    • William, going along with your truck engine into a truck application, we would suggest a truck cam. Summit Racing just released their Pro LS Truck cams on July 4.

      They are intended to maximize torque and midrange with a strong top end. The Stage 1 truck cam has a noticeable lope and works with stock springs. It makes a ton of power and is good in a daily driver. Not that you have to worry about it running a manual trans, but the Stage 2 cam is about as much as you would want with a stock converter and has a steady lope. The Stage 3 works with a 2500 converter and has a more aggressive lope. The Stage 4 is pretty serious even yet. It works with a 2800 converter and makes power higher in the RPM range.

      Stage 1 doesn’t require springs, but Stages 2, 3, and 4 are designed to work with LS6 springs. You can read up on the descriptions and specs a little more by checking out this article.

      One thing you mentioned is you’re doing a fair amount of street driving. If your 750 double pumper isn’t driving the way you hoped for, the newer Demon Carburation carbs (made by Holley) are getting good reviews. They have small primaries and extra-large secondaries and people say they run like injection. You could get by with a 625 cfm with your cammed L96, but the electric choke composite bowl 750 is a match for the double pumper. Give Summit Racing a call at 1-800-230-3030 if you have any further questions on any of that to help you make the best choice.
