I buddy of mine picked up a 09 said LQ9 it has 823 heads on it - I have no idea other than this is what I was told. I asked if it has VVT or DOD- he didnt know said its iron block 6.0 with 823 heads. I'm looking for a motor for my son for a turbo project. it has a bad cam with a flat lobe in it - if you can shed any light on what thios may be- and I have searched and searched and most info tells me 823 is a L92 head- did they put em on 6.0? I was wanting to install a LS6 cam and maybe some 317 heads for turbo and keep the 823 and intake for me - advice needed.... ok and is there a 90mm TB what will bolt up to ls3 intake for cable?

Its a Gen IV LY6 or variant. 6.0 iron block with the "LS3" rectangular port heads.

It came in the 3/4 Trucks, SUVs, and Vans. It does have VVT but not AFM (DoD) and about 9.6:1 static CR.

Have to change the cam and the timing set...

cool so i can install a ls6 cam and ls2 timing set and roll with it?

Ideally yes, but us people are going to recommend a different cam in most aspects for those LS3 heads. They change the game considerably.

I've got a stock LS3 cam laying around I'll mail you for cost of shipping (~$20) if you want it. Less then 1000 miles.

The 823 heads make it an LY6. It needs the lifters changed, timing set, valley pan, phaser removed, etc. to make it high performance (cam). They do make dod cams, but I wouldn't use one.

LY6 doesn't have DoD. Lifters and valley cover are fine.

dang this is getting confusing! I guess when I get it I can pull the valley cover to see if it is DOD. so even if it is DOD - that can be removed? could it have DOD and VVT?

I stand corrected. The LY6 DOES have the 1 bolt cam and the VVT phaser, those need to go for a cam swap. You need the LS2 front cover, LS2 timing set, and cam to delete VVT.

how would this setup be with LS7 cam? - thinking a turbo is in its future- funds allowing

1 Bolt cam has zero to do with VVT, and why would you change the front cover?

zman1969

iTrader: (91)

have you seen one? the VVT retards the camshaft for emmisions and the connetor for it is at the end of the cam on the cover you cant mount a LS1 water pump because of this. so you go to the standard 3 bolt timing set eliminating the cam phaser and run ls2 cover so you can use the ls1 accy.
well I now have the motor at home and its amazing the changes they have made since 1997.
anyone have suggestions on the ls7 cam? do i need 1.8 rockers or run 1.7's?

All ls3s have a single bolt sprocket. If you need to change the cover to get stuff to fit then go ahead, but the sprocket isn't a problem... you just use whatever sprocket your cam needs.
