6.0L build/ Stroke,charged,or turbo? I am picking up a 6.0L later this week and was curious about how other people's builds are going. See them on here all the time so I figured the knowledge would come from here. It's an LQ4 and it will be a fresh build so I am going to be taking it slow. Was also curious if the bare block(LQ4 & LQ9) were any different? All parts will be finding a new home unless they can be used for the build. So, stroker, supercharger, or turbo charged?

I think you will find that most are building turbo set ups here and for good reason! I guess to start with what are your goals for the car? Uses for the car? What is the 6.0 going into? What transmission will you use? Kinda hard to make any suggestions without a lot more information.

If your going with the lq4 get the 01 and up so you get the alum 317 heads , that's what I'm building now and the lq4 have dished piston compared to the flat tops on the lq9 (turbo)

Sorry for the lack of info.It is from a 2002 Silverado. Just got home from picking it up. It is going into a 2000 Firehawk. Have the LS1 now but just want to take my time, build something with it, then try it out. I want a road course car. Taking turns at the dragon. It is an LQ4 with the 317 heads. What should I keep and what is not needed? I know the intake, heads, exhaust, and cam are coming out. And I do understand the dished pistons are better for boost when it comes to your compression ratios. Should I keep the crank, rods, and so on? I wouldn't mind a good amount of HP and TQ. Would deff like to beat most mustangs at everything. I.E. red light to red light, or some road courses. And I wouldnt mind putting some SS's to shame as well. LOL

The guy I picked it up from said there was about 200,000. He said the motor still ran so we will see when I pull it apart and send it to the shop. Hopefully no issues. But if there is, hopefully can be fixed. Kind of worried but I am sure it will be fine.

Honestly I would keep the heads as well. There are people making big hp with those heads. Port them if you want and of course new springs and retainers. I am actually using those same heads with just a valve job, new springs, trunion upgrade and new pushrods and lifters.
Some Bosch 96 lb injectors, a cam and twin turbos would make a fun road course car. Maybe twin front mount Borg Warner s366 turbos and you should be good to your goals with quick spool and good reliability. The 93 octane will be your limiting factor without meth.

Well a small change of plans. I was going to place this motor in my DD firehawk. Just bought a roller minus wheels, hood, engine, pcm, trans, and a few other small pieces. Once I get that, game on. I really want to make the front end from front quarters and bumper a one piece. Is this possable since there is no frame? Update on motor.... digging in to it. Found fuel sitting on top of two of the pistons. Weird. I know I didnt do that so must have been from whoever pulled it out and didnt plug the fuel lines. Taking the bottom end out maybe this weekend to see what it reveals. I have an extra set of 853 heads I think they are. Dont know what I am going to do with those.

I see where the it says 6.0L on the block but where does it say that its an LQ4? Or is there a part number that is related to the LQ4? I did pull the 317 heads off. Looks like there is a little rust on the inside of the cylinder walls but a bore will fix that. Can you stroke it with dished pistons and throw a turbo on it? Or would that be too much?

I have a 180,000 mile 6.0 in my fairmont with a 80mm . It works great . It's completly stock it's never had the valvecovers off. And I never took the oil and grime off the motor before I stuck it in the car.haha!

Can I make 600+ HP with a stock bottom end? I have the part numbers from the block...is there a way to tell what it is for shure??? i.e. LQ4 or LQ9? It does have the 317 heads on it but the guy I bought it from said he wasnt sure what truck it was exactly. He did say it was an 02 ish...lol PN# 12551364....also stamped is GM-SMCO and 6.0L

NVM on the last about what part number it was. The LQ4 and 9 have the same stamps. Would have to pull the PN off the pistons. But the pistons are dished so I know now. But the question still remains if I can get 600+ from the bottom end?

Started crunching numbers and trying to figure everything out. Dont need to do a big bore unless necessary. Should I push for a 408 with dish pistons to run a supercharger/turbo? I think I could still get 408 CID at 10:1 CR ish and still push 10 PSI? Is that possable? Anyone running this type of set up? Seeing whats possable. Was going to run 8.5:1 with big boost but I still want it to have its own compression and not rely on boost alone.
