What is the biggest LS engine?
The LS7 is the standard engine in the Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest LS engine offered in a production car. Unlike LS1/LS6, LS2 and LS3 engines, the LS7 uses a Siamese-bore cylinder block design - required for its big, 4.125-inch bores.
In terms of displacement, the 4.8L checks in a 293 cubic inches and while down on displacement to the larger 5.3L and 6.0L, the short-stroke 4.8L is an interesting departure from the run-of-the-mill 5.3L. Given the minimal displacement of the 4.8L, we couldn't help but call this project Mini Mouse.
- The Vortec 4800 LR4 (VIN code "V") is a Generation III small block V8 truck engine. Displacement is 4.8 L (293 cu in) with a 96.01 mm (3.78 inch) bore and 83 mm (3.267 inch) stroke. It is the smallest of the Generation III Vortec truck engines and was the replacement for the 5.0 L 5000 L30.
- The largest version of the Generation I small-block was the 400 (6.6 liter). It was the only engine available with both the 4.125-inch bore and the 3.75-inch stroke crankshaft. It debuted in 1970 and was produced for 10 years.
- The L18 (496 in³/8.1 Liters) debuted in 2001. It was a long-stroke derivative of the 454 in³ engine (same bore) built in Tonawanda.
ITS 325 CUBIC INCHES. Do the conversion or easier yet, go to www.Chevrolet.com and look for yourself under the 5.3l engine specs. A 350 small block is actually the engine found in earlier model chevrolets and is 5.7liters.
- The V6 has ample power for driving around town or on the highway. This engine probably won't hold you back when it comes to towing and hauling light loads, but the larger engines are better choices for heavier duty. The next available engine is a 5.3-liter V8 that produces 355 horsepower and 383 pound-feet of torque.
- The figure refers to the rounded-off displacement of the Mustang's pushrod V8 during the early '80s to 1995. Now, for the first time in a decade the "five-oh" is poised to return. Let's take a closer look at the new engine. The original 5.0 V8 displaced 302 cubic inches, or 4.948 liters.
- The LC9 engine is a 5.3L, Gen. 4, aluminum small block engine used in GM trucks and SUV's between 2007 and 2011. For marketing purposes, it was also known as the Vortec 5300.
376 cubic inches
- It is rated at 303 horsepower and 323 lb-ft of torque. A legend in its own time. The LS7 is the standard engine in the Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest LS engine offered in a production car.

- This video from The Fast Lane Truck pits the new 2017 F-150 Raptor with its 450 horsepower EcoBooost V6 against the original 2014 Raptor using the naturally aspirated 6.2-liter V8 with 411 HP. Not only does the 2017 model have both a horsepower advantage, it has a massive amount of torque on tap at 510 lb-ft.
