Is the LY5 a good engine?
The LY5 engine is a 5.3L Gen. IV iron-block engine used in GM trucks and SUVs between 2007 and 2009. 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.
What is an LH6 engine?
The LH6 engine is a 5.3L Gen. IV aluminum engine that replaced the LM4 in 2005. It was the first Gen. IV LS truck engine and offered Active Fuel Management (AFM). Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era.
What do camshafts do?
The camshaft activates a cylinder’s intake and exhaust valves. One lobe will activate the intake valve, followed by a second lobe that activates the exhaust valve. As the shaft rotates, the valves will open and close in the appropriate timing.
Should I delete 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.

Consider installing a performance camshaft. Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly.
Can you disable VVT?
Eliminating the VVT system is required when swapping to a non-VVT camshaft. These cams offer higher valve lift and longer duration for more performance. A VVT delete kit removes the VVT components and replaces them with standard parts.
Is VVT engine good?
There are many benefits to using VVT and virtually no drawbacks. One benefit is an increase in maximum engine speed (and therefore more peak power) – as much as a 25% increase. Low speed torque is also increased, providing better handling and drivability.
