LS1 or 6.0L for my 2000 Camaro

**My00Z28** · 09-13-2010, 08:57 PM

I have read many threads on my question but still dont know what i want.

Ok this is my deal. I have a 2000 Camaro Z28 A4 and i want to build mean power. i also have a 6.0L out of a GMC Yukon XL Denali that blew the rings in it and needs to be at minimum honed out. Im going to be giong to School for Automotive High Performance and am going to be building one or the other with full machining to the whole longblock. Im looking to see if the 6.0L(iron) block is better than the 5.7L(aluminum) block? Im NEVER planning to spray but will consider turboing it. Id rather keep it NA but people always want more.

What are your opinions on the info iv left you? Im planning over 500rwhp!

if you need more info let me know!

what year 6.0. imo the 6.0 can be nasty with boost. i honestly dont know whether it is the lq4/9 or another block but the lq series are common builds with stroker motors. lots of lq9s out there stroked to about 402-408 and running 500rwhp through m6 cars NA. a4 would be hard to hit but i like the idea of an e.t. at the track as a goal not necessarily a hp goal. once you add in the boost you will easily eclipse the 500hp mark with s/c or t/c set ups. forge it if you plan on boost and the extra cubes from the stroker kit will make power regardless if it is NA or not. fuel system and drivetrain upgrades are absolute musts though. if you go through with the build dont cut corners. get it done right the first time or it will come back to haunt you.

the 6.0 is out of a 2002 if im not mistaken i think its a lq9? i plan on building everything in the drivetrain as well i probly wouldnt boost it for a while but always a possibility. my e.t times im not sure i like to do stuff to a car then go see what it will run(idk if thats the right way to do it but its just me)? i mean i have both of the engines complete with everything but i need to make up my mind on which one i want to build. is the 6l that much better for power and reliability? compaired to the ls1?

I would do a stroked lq9 to a 408 and go all motor that way and when you want more then supercharge it or turbo it.

How many hp has those engines? The ones from the 02 denali
I didn't knw it was possible to put em in a camaro
My friends has that motor and he told me I could have it.
What do I need for the swap?
Sorry for stealing diz thread lol

i think the 02 denali's make around 320hp stock. the motors should be just drop in? they are all from the same family of the "LS" motor! being stock they arnt worth the extra 10hp? and the 80lbs IMO to do an engine swap, but if its or going to be built like im planning then go for it.

**98maro** · 09-13-2010, 11:12 PM

I ask cuz my motor needs to be rebuilt some day not far from now.
And idk if I just rebuild it or buy another one and get a cam and heads.
Or just rebuild mine and get cam and heads too
So I'm kinda confused
My car has 122xxx miles and it's burning oil
The motor I'm talkin bout has 50xxx miles
But is leaking oil

**My00Z28** · 09-13-2010, 11:19 PM

it all depends on your needs/wants?

**98maro** · 09-13-2010, 11:22 PM

True. The main problem is the emissions. I can't go to crazy on cams or LT headers cuz I won't be able to pass emissions.
I'll figure something out.
Thanks for the replies

lq9 is a direct swap. you will need to tap a hole in the block for the alternator(an accessory for sure) i believe but every thing else will swap straight over. no wiring harnass troubles no bellhousing troubles. its not that the motor is a clear cut above the ls1 because they are damn near the same casting with almost exact same internals. obviously a bit bigger crank and 6.0 heads and all iron as opposed to aluminum. both are great designs. the iron has a lot more potential when it comes to more cubes. you can stroke and bore it out a lot more than the aluminum ls1. the stock sleeves on an ls1 are small. very small. if it is a low mileage car they can be honed at best. high mileage will most likely need resleeved(expensive). obviously the iron lq9 has tons more room with the ability to be bumped up to the low 400s in cubic inches. more cubes are automatic power in all performance set ups. the extra cubes show their worth in any set up NA, FI, or NO2. the lq9 is a lot more friendly to the pocket book because it is iron. if you go so far as to resleeve your ls1 you will most likely be spending more money than stroking the lq9. all that just to be able to be stroked beyond stock ls1 sleeves are capable of. so similar money for an ls1 that is ready to be worked on or an lq9 that is ready to install. non forged lq9 mind you. if you forge the stroked lq9 it costs about the same as resleeving and stroking(non forged again) the ls1

well in both cases they both need forged interals but from what your saying its cheaper and easier for me to build the 6.0 than it will be to even resleeve the ls1... and cant the inturnals of the 6.0 hold like 500hp?

forged internals needed for FI setups not absolutely necessary for NA builds. but cast stroked bottom ends hit 500 and have held up well from what ive heard. like i said before do it right the first time or it will be costly. i would get it forged from the beginning if there is a chance of going FI in the future. so you dont end up spending extra down the road. forged can handle so much more than any cast part obviously but i am big on not double spending because money easily disappears that way.

ok i just did some research on the motor im pretty sure its a lq4... the motor is all taken apart and i went out and looked at he pistons... but the lq4 and lq9 shouldnt make a difference to me if im planning on replacing the internals anyways right? or are the heads that much different?

not a huge difference. i think it was minor things like a cam and different valve springs. cam was a tad smaller in the lq4 and the lq9 had ls1 cam. the cam should be different after the stroker kit anyways so not a big deal. all you valvetrain will be swapped after the stroker kit is in.

**My00Z28** · 09-14-2010, 09:12 PM

are the heads on that motor good as well for everything? or should i use the ls1 heads?

ls1 5.7 heads will up compression pending on how you get them worked. ported ls6 heads are 5.7s also but they are what you want for NA build. much better flow all around than ls1 heads are capable of. ported 6.0s to keep the low comp. lower comp means a lot better for boost. milled and ported raises comp ratio also. but with a higher comp ratio will come higher octane fuel. but i dont expect a mild high comp ratio stroker to need higher than 91/93 octane. i dont know the formula to figure the comp ratio but the stock ls1 is like 10.1:1. the stroker would be higher comp if it had the 5.7 heads. how much higher depends on a few variables but if your looking for 500rwhp from stroker motor through an a4 you will need the higher comp. a built and stalled a4 works great performance wise, but it will never give you dyno queen numbers. so you will need more power to hit 500 NA with and a4. and one more thing that i cannot stress enough, that i failed to mention for some strange reason, is a great tune. not good, great. a proper tune will give you performance, driveability, and reliability no matter what the vehicle.

and what am i looking for when buying a rotating assembly? i found on Texas speed (under 99-04 Trucks, ENGINE & VALVETRAIN, ROTATING ASSEMBLIES, and the 408 stroker kit)that gives you aton of options for the 408 stroker i know i want it balanced and i want bearing eagle forged crank what about pistons and stuff like that?
