3.5L vs. 3.5L VVT

[G6V6Lover]

Hello!

OK, so here's my first question since joining...hopefully I haven't duplicated this question, but I probably have!

What is the difference between a 3.5L and 3.5L VVT? What are the advantages/disadvantages of each (if you can call it that)?

Thanks!

The 2007+ 3500vvt (LZ4) has variable valve timing which gives it 24bhp. But it doesn't have as good of fuel economy as the 2005-2006 3500 (LX9)

VVT=More horsepower at higher revs

And, oh yeah and enjoy your stay

What is the difference in HP and MPG in the vvt and non-vvt??

LX9: 201/220 and i had 22/35 pre tune
LZ4: 224/220

Same torque tho, do u think that was maybe to keep down the torque steer?

Re: 3.5L vs. 3.5L VVT

I do think the LZ4 has more torque management.

Thanks for the replies.

So torque is the same, but HP changes. I have the 219 HP, so I guess that's the 3.5L? Interesting that there are all these variations in engine, even within the same size (in addition to the traditional 4-cylinder, V6 3.5 & 3.9).

If you have an 09 than you have the LZ4 3500vvt. The '08s and up have a third cat.
