v6 forged internals?

[76z28]

Does the v6 have forged internals?
and how much power can it handle without upgrading them?

I've never heard anything about the LLT motor having forged internals so I doubt it but don't know for sure.

In the V6 section there has been some talk and it looks like the first bottleneck is the injectors maxing out in the mid 400's.

Features found on the 3.6-liter VVT DI include:


•Aluminum engine block and cylinder heads
•Dual overhead cams with four valves per cylinder and silent chain primary drive
•High-pressure, engine-driven fuel pump
•Advanced multi-outlet fuel injectors developed to withstand high pressure and heat
•Stainless steel, variable pressure fuel rail
•Four-cam phasing (VVT – see description below)
•11.3:1 compression ratio
•Aluminum pistons with floating wrist pins and oil squirters
•Polymer coated piston skirts
•Forged steel crankshaft
•Sinter-forged connecting rods
•Structural cast-aluminum oil pan with steel baffles
•Electronic throttle control with integrated cruise control
•Coil-on-plug ignition

The pistons are hyperpathic... I mean hypereutectic... which means while they are strong and are very wear resistant, they are also very brittle...

Now I have not see the pistons in our 3.6 LLT but cars today tend to have rings are very close to the top, to reduce emissions, it makes the ring landing (the area of the piston about the rings), susceptible to cracking and breaking off during stress and loading, like boost or detonation...

So, my guess is the pistons are going to be one of the weaker links...
