I have some doubts! Right now I have a 6.0 lq9 on My 01 silverado all boltons, cam etc. There's a 6.2 out of a 2010 escalade that I can get My hands on for 1k. I know that all My boltons fit right up on the 6.2. But does anyone know if its worth the swap? And if anyone has done it does it really make enough differece? So if yall can share some info or HP numbers please post them.6.0 lq9 vs 6.2 l92....
THe l92 heads outflow half the aftermarket 6.0 heads. For 1k, I can't see you going wrong. I love how my 6.2 runs.
6.2 bro 6.0 345hp to 403hp6.2
6.2 is pretty sweet, but I don't think I would bother if you already have a LQ9. You are going to have to spend some cash dealing with either using the newer PCM or converting the crank sensor to the 0411. You will have to do something with the throttle body too.
You could always spend the 1k you were going to use to buy that motor and put it towards the l92 heads and put them on your Lq9 if you dont want to go through the trouble of doing the swap with PCMs and what not. But those new 6.2s are sweet for sure!
Why not just buy the 6.2 take the stuff you want......aka the heads and part out the rest of it I am sure you could get most of your money back selling it off on the forums.
That's what I'm talking about. All of you make sense. That's why Im not sure what to do yet. My next step was going to be l92 heads but now with the complete motor at the same price as the heads its tempting. I guess ill wait and see which motor gets the most thumbs up.
If u can get the whole motor for that... I'd say take the heads and intake and sell off the rest. The head intake combo is where the 6.2 shines. With those heads milled down to get your cr up u would be very happy. And wouldn't have to deal with the problems stated above...
Yup buy the motor and use the heads and intake on ur lq9
I'd use the whole motor. You gain 12 cubes and bad ass heads. The converter box can be had for around 300 bucks IIRC.
And the 6.2 is aluminum, so your saving an ass ton of weight. You could re-coop a lot of it selling the LQ9, they're still worth a fair bit. If I could get an L92 for a grand I'd be on it like a fat chick on a cupcake.
So you guys are saying I could put L92 heads on my LQ4 and that intake? What will that be worth as far as gains with a small cam?
Yep thats correct, As long as you run the Ls3/L92 intake mani. You should see 400+ depending on cam..Quote:

wouldnt he have to mill the crap out of the l92 heads to work on a lq4 ? to meet a decent compression ratio?
the decks are already thin, dunno if i would wanna mill ..040+
i agree with frenchy and derick also, for a grand id do it in a heartbeat and wouldnt think twice ;)
hahahaha i see you didnt think twice neither the motor is foresale on hpt ;)
Just buy it bc if you change your mind you can just resell it
Good catch skeet, For the Lq4 he would need to mill the crap out of them for sure.
What would you expect the CR to be on the LQ4 with unshaved L92 heads (stock head gaskets)?Quote:

i guess milling them a few cc would get him close to 10:1 ? but owuld it be worth it
You may be right skeet, I did a quick search and saw 9.5:1 so you may be right.
I am sure milling .020-.025 would get you 10:1, Which would be a decent CR, But not sure if its worth it. On a Lq4 I would do a bad ass set of milled and P&P 243s and net you around 10.5:1-11:1 and call it a day.
Me personally ... I was thinking of a 408 LQ4/9 build with L92/LS3 heads with a TVS2300 blower on top. Just wondering if it would need to run some thicker head gaskets or work the combustion chambers over to drop the compression ratio down to about 9.0-9.1:1. With the right cam, should be in the 800fwhp range for around $10-11k.Quote:
