agreed, LQ9 (if your motor is from an escalade it'd be a 9) would be an iron block motor.
also on the front of the block behind your p/s pump somewhere there would be a 6.0 stamping.
Stock heads on an LQ I thought were 317s?
is an 823 a 5.3 head? iuf so they probably swapped em to get compression up, but.. LQ9 already has flat top pistons so.. I'm at a loss there.

Point the vehicle in a safe direction, put it in drive and press the accellerator all the way to the floor. If your face looks like this:

It is a 6.0

A LQ9 should have 317 heads. What yr of escalade did the motor come out of it might be a 6.2L L92 motor if it has those heads on it. A 6.0L block should have 6.0L cast into it like in the pick below.
A L92 block will have 6.2L cast into it.
A 4.8/5.3 block will have 4.8 and 5.3 cast into it.

SUPPOSEDLY.. an Lq4/9 can get ~400whp with a "cam only."
I admit I don't believe it for a second on a 4, even though people have claimed it in more than one place, I think they're just all liars.
but.. in the probably HUGE chance that it's just my typical cynicism.. yea, a simple cam swap on an Lq9 could put you above 400 at the engine easy easy considering they already had ~345? I think with a truck cam.
if you have L92/LS3 heads, they're probably rectangle ports, which would make sense. The LS1 can't run them because of the bore size.
L92 heads are cheap, but you have to upgrade the springs n whatnot.
if you have an L92 rect. port setup you probably have an ls3 intake as well. I think they look SLIGHTLY different, you probably have some adapters and things on the intake to make it work witrh your car if that's the case.

It might be an LQ4....It might be an LQ9...I just put LQ4 in sig cuz I wasn't real sure....Idk the differences
And Idk what it has internally but might have a mild to moderate sized cam...has green top injectors...FAST TB...Hooker LTs...823 heads....but still needs a good tune...idles at 1350 which is why I can't tell real well what the can is like

what cam? I've got a 233/239 tsp cam going in my LQ4, planning to do 5.3 or ls6 heads, (milled if I go ls6) and I don't think I'll hit the 400whp mark with it.
that idle sounds really really high for a DD car. Is it an aggressive cam? why the heck would it idle that high?
Lq4 and LQ9 are minor differences. Basically, the 9 has flat top pistons and beefier rods. The 4 has dished pistons.
they did this so that they could make the 6.0 int he escalades a "high output" motor and not have to change the heads. It just increases the comperssion from like 9.5 to 10 or something.. I don't even remember now the stock CR. It did make about a 45FWHP difference tho with the compression change.
4s are a lot more common than 9s, and when you do find a 9 it can go for 2x the price of a 4 in a salvage yard.
