Is a L77 an LS2?
L98/L76/L77 Introduced in 2006, the L98 and L76 are 6.0-litre variants of the LS2.
Does L77 have VVT?
Specifically, the 6.0L (364ci) RPO L77 engine has AFM enabled, but does not use VVT. (The L77 also includes flex-fuel capability, allowing it to run on both gasoline and E85 ethanol.)
How much power can you get out of a LS2?
The LS2 engine block has a 4.000-inch bore diameter. The cylinders can be bored to 4.030 inches. However, we recommend leaving them as thick as possible when running boost. The block can handle 850 horsepower.
Do manual L77 have AFM?
L77 for manual transmissions Models with the L77 engine and manual transmissions did not have an active AFM system and had a higher power output because the L77 AFM engine was detuned to 1) improve refinement when the AFM system engaged and 2) reduce fuel consumption.
Should I delete VVT?
If you want to upgrade your camshaft and keep the VVT system, you will need a Camshaft Phaser Limiter. If you want high performance from a bigger cam, you will need to delete the VVT system.
Should I keep VVT?
As for keeping or deleting VVT, the benefit of keeping VVT is that you gain low end torque. The drawback is that you lose high end hp compared to a LS3 cam. Many people swear up and down that a VVT cam is the way to go, while others swear up and down to delete VVT and do a LS3 conversion.
How much horsepower can a CAM give you?
Does a camshaft increase horsepower? Yes, a camshaft adds 10 to 20 horsepower depending on the setup. To get the full potential of the high-performance camshaft, you’ll have to swap out additional components like the air intake, exhaust manifold, injectors, and valve heads.
What is DOD in L77?
Active Fuel Management (AFM) or displacement on demand (DOD) removal kit is designed to eliminate the cylinder deactivation system on GM V8 engines.
How do you delete AFM?
How to Delete AFM
- Replace your camshaft with a non-AFM camshaft.
- Swap out the AFM lifters for standard lifters.
- Replace the valley cover with a flat, non-AFM valley cover.
- Disable the AMF system with the Range Technology Disabler, or custom tune it out.
- Plug the pressure relief valve in the oil pan.
What are the specs of a L77 engine?
GM 6.0L V8 Small Block L77 Engine Specs Type: 6.0L Gen IV V8 Small Block Displacement: 5967 cc (364 ci) Engine Orientation Longitudinal Compression ratio: 10.4:1 Valve configuration: Overhead valves
What replaced the L76 and L98 engines?
With the release of the VE.II and WM.II range in September 2010, the L76 and L98 were both replaced by the L77 engine which had E85 flex-fuel capability. For models with manual transmissions, however, the AFM system for the L77 engine was not enabled.
What is the difference between L77 and L77 AFM?
Models with the L77 engine and manual transmissions did not have an active AFM system and had a higher power output because the L77 AFM engine was detuned to 1) improve refinement when the AFM system engaged and 2) reduce fuel consumption.
How can I Make my L77 engine run better?
Getting a tune makes it easier to dial in a bigger cam and injectors later on. Before going to the tuner, we recommend installing a colder thermostat to open up the L77 tuning window. Below are some more upgrades you can make to improve the performance of an L77 engine.
