The 6.2L L86 engine is the base for the L87 engine. The L87 features integral components for Automatic Start/Stop capability and Dynamic Fuel Management, which improves fuel efficiency. It also features Oil-jet piston cooling and Direction Injection. The two-stage oil pump also comes standard.
4.3 liter V8
The 4.3 liter V8 is part of the new generation of small-block engines developed by General Motors. It debuted in the 2014 Chevrolet Silverado 1500. Like the 6.2-liter V8 and 5.3-liter V8 engines, it uses a dual overhead valve design. The 4.3-liter engine has a single camshaft located in the center of the Vee.
The L82 was the base engine for the new Hummer H3 in 2008. The Vortec 5300, which was named after it, was the base engine of the Hummer H3. Its predecessor, the 5.3L V8, was only offered on lower-trim models. The 5.7-liter L86, on the other hand, was used on mid and high-level trucks. Despite the similarities, the truck engine used a deeper oil pan and a longer intake manifold.
Direct fuel injection
Changing to a direct-injection system can boost your car’s performance. By pulsating the injector several times to get the perfect fuel/air ratio, direct-injection systems are more precise and make your car’s engine run leaner and more efficiently. Direct-injection systems work with a high-pressure fuel pump that can deliver up to 2,500 psi of fuel. This pump is usually driven by a camshaft and has different output and displacement settings.
Direct fuel injection for l86 engines can boost the power of your car’s engine by as much as 30%. They are able to do this by utilizing a set of specially designed injectors with high flow direction. The injectors have a lobe that is 7.85 mm wide, which results in 2.6 cc of fuel per revolution of the camshaft. Flow testing has shown volumetric efficiency to be over 90%.
Oil-jet piston cooling
Oil-jet piston cooling is a crucial component of a vehicle’s cooling system. It keeps the piston cool and increases the durability of the engine. The L86 engine has two types of piston cooling systems: direct-injected and oil-jet. Direct-injected engines require more oil to cool the pistons, and they also require more frequent maintenance. An oil-jet piston cooling system will reduce the amount of oil needed for the pistons to operate properly and maintain durability.
The L86 and L87 engines are similar to the LT1 engines in Camaros. They both have the same camshaft part number and have similar internal components. The differences between these two engines are the larger intake port and a larger throttle body.
The 2014 Chevrolet Silverado and Sierra engines feature cast-in iron cylinder liners and aluminum engine blocks. Using data from GM’s racing programs, engineers developed a deep-skirt design to maximize strength and reduce vibration. The engine’s four-bolt, cross-bolted main bearing caps are bolted to the block with structural cast aluminum oil pans. The block also features a structural aluminum oil pan that eliminates coolant passages.
Six-bolt main caps
Main caps are an essential part of your engine. Not only do they keep the engine from overheating but they keep the inner parts of the engine from spinning, which is beneficial for performance. Choosing a good main cap is an important first step. You should consider the material, design, and repeatability of the cap. This will ensure that the cap is exactly as you’d expect it to be and that the oil pressure stays where you need it to.
Six-bolt main caps are designed to tighten into the lower end of the crankcase and stabilize it. You might also want to install one if your engine’s block is made of aluminum to help with torsion. Regardless of what you choose, be sure to check the dimensions of your engine block before purchasing new main caps.
The cast-iron block for a 6.6L LT engine offers several advantages over the stock aluminum engine. First of all, this block is safer than its aluminum counterpart. Even aftermarket sleeve sets improve the strength and rigidity of the block, but do little to increase the block’s weight. When the engine is stressed to produce high horsepower, the sleeve may break, tearing the main webbing and casting out of the block.
For the most part, GM trucks and cars are built with cast-iron engines. However, some models are built with aluminum blocks. In addition, many of these engines are equipped with cast-iron cylinder liners. These engine blocks were designed using data from racing programs to maximize strength and minimize vibration. They also feature four-bolt cross-bolted main bearing caps and a structural aluminum oil pan. These features make GM engines quieter, even in the harshest of conditions.
