Title says it wrong.....I an Meaning an LQ9 Motor.....NOT an L92

I want to know about the LQ9 Motor, specifially an 08 model.
I don't know much about this engine but I can buy one pretty cheap right now. It's not for the SS, but for my future project "Swapnoma".
I was getting ready to pick up
a fresh 5.3 , but then I came across this.

Tell me about it O' wise knowledgable engine guys.

The biggest difference is just the VVT/cam phasing. It has a slightly heavier valve but I doubt you would notice the difference. It will come with the truck style intake which makes more power and torque. I'm not sure about the piston differences.> I didn't know there was one.

I know it has Flat top pistons, I do know that. I know its a 345 HP motor.
Its going in roughly a 3200 pound truck with either a 4L70 or 4L60 Behind it, unless I can get a 6L80 to work with it.

I was planning a 5.3 with 243 Heads and a nice cam, but then I stumbled upon this motor and thought I would explore the option of it. I know right off the bat its a bigger motor, but I am not building the truck to be flat out fast, just more of a Street rod/Fun Truck type project......But of course it'll make a few passes.

The LS3 has slightly higher compression ratio of 10.7:1 compared to the L92 of 10.5:1. I'm not sure if thats from cylinder head design or piston design. I know all the service measuremants for both cylinder heads and pistons are identical.

The lq9 has the 317 heads which are the same as 243s except for the chamber size,so 243s would be a good bump in compression.Otherwise its basically a iron ls2.

LOL! I love it when people read and respond off a simple thread title rather than the opening post. :doh:

The LQ9 is an iron 6.0, with cathedral ports, with 317's or 853's (317's have better flow) and both have large combustion chambers but still yields 10:1. All these "370's" you read about the guys having are built from a LQ9 block.

Depends on year model LQ4. Earlier year models had long head bolts and different sized cam bearings. A slightly weaker setup to the LQ9's.
