Another 6.0 build. Let me know what you think.
 

Like I said this is going to be put in my '00 rcsb dd. The build will consist of a na '03 6.0 block (.030 or .040). Dont know the bore yet as I will take it to the machine shop fri. For pistons I will use sealed power hypereuctectic dished, 243's w/ a little massage to them. The cam is going to be GMPP ASA cam: duration @ .050in 226/236, lift .525/.525. Shorty headers till I get enough money saved up, trying to get it done as my dad is sick with cancer and I know his love for cammed Chevy's is like mine. K&N cai, the tranny will get done after the motor is installed it ill be a 4l65e with a tbss tc, the rearend will get 3.73's and tru trac.
I have the FAST 102mm intake but a friend of mine said that I should go with the stock 5.3 intake, Whats you thoughts and input on it? Thanks for your input.

Its the 4.2 trailblazer stall you want, not the SS. I'd run a NNBS/TBSS intake if you want to save money on the intake.

Sounds like a nice setup man... only thing I'm curious about is the cam choice. Do you already have it? My experience would recommend good proven 6.0 cams like the classic tr224 or the 228r.. don't like going into the 230's in a truck. Get some longtubes as soon as you can and should be stout. The 102 is a nice piece but a tad overkill on a cam only 6.0 .. I say stay with that stock intake for now. Was the 102 the lsxrt for trucks or the car version?

The cam is a bad choice and the intake is very expensive for what you are running, I would use a TBSS or NNBS truck intake for now at least.

@robert91rs- Whats the difference between the two?

@kazfan30- I have the lsxrt truck intake, and I have the cam already to, but Ive seen some good things of it. Well see how it goes. Why do you not like hit the 23x range?

I say definitely run the intake since you have it.. it will be a gain and surely won't hurt it.. lol. I personally like smaller cams in ls motors overall but especially in trucks. And since you going tb tc its a small stall so I would keep a torquey cam to get that heavy girl rolling. ;) you may end up liking that cam but a 228r would be beast with that intake and boltons. Also look into circle ds stalls I picked my 3k for under 400.00 and it did great! And will like that setup. Good luck man

Well I havent got the tc yet so I was thinking maybe I can get a circle d tc since the tranny wont get done till next year.

Nice set up

@LA Simple Sam- Thanks bro, just trying to see what I can run at the track with this budget build.

The TBSS stall speed is similar to your factory stall. The 4.2 stall is in the 2500-2800rpm range, but if you have the cash CircleD is def your best option.

As for the Cam and intake, I tend to agree with some of the others. If you sell them you could get a NNBS/TBSS intake and a TR224/TSP224 cam kit.

I know everyone doesnt like the cam or intake but does anyone have any hard information why not to use them. Like dyno sheets with exact same setup to the T. I mean no problem with changeing things up just like to see solid evidence and not hear, hear say of what works.

In my massive search of putting a cam in my truck I've come to realize bigger isn't always better... Especially in our heavy ass trucks. Now in a car that cam may be sweet as hell, but in a truck it's gonna throw the torque way too high especially for a 3k stall. No I don't have any sumo sheets or any of that shit. I also haven't drive a truck with a cam that big but I do have google and pt.net search button. Trust most of these guys. They've been around the block and know what they're talking about. Idk how many posts I've ready that guys have taken out their 23x cam and ran something smaller and it performed a lot better, and worked a lot better for the set up they were wanting being anything from dd to weekend warrior. I am what ya call a noob but I've done a lot of research about cams and read numerous builds on the subject and this is just what I've learned so take it as you will..

It sounds badass bro once it's ready u gonna fly do doubt bout that

The intake is great, but it's a thousand dollar set-up that may make an extra 5-10hp on a mild 6.0 build. Keep it if you like, it certainly wont hurt anything, or trade it for a stocker and some LTs that may be worth 20-30hp.

If there would be someone willing to trade that would be a good deal, but everyone here has the same view point as to not like the intake.

Not a bad build list. I'd probably want ~3k in a stall converter. Plus the 4.2 trailblazer converters are heavy, compared to aftermarket. I'd also look at a set of pacesetters over the shorties. I run them. They fit good. Cost me ~$500 for the headers and y-pipe. That was in 2010, I think they are cheaper now.

If it were me, I'd run a 230s cam all day long, twice on Sunday. I ran my 230s cammed 6.0 all last week, back and forth to work. Don't be scared of a bigger cam. A reg cab truck isn't that heavy. Funny thing about a bigger cam. I always see the small ones up for sale in the classifieds.

A small cam with flat top pistons and 243s isn't going to live up to its potential. You'll have so much compression, a small cam would actually hurt.

Its a tough call on the intake. The 102s make ~15-20 more hp over a tbss/nnbs style and ls6 intakes. But you could probably swap the intake for a good set of used, ported 243s. Then run a tbss/nnbs intake.

Here's my build and dyno sheet:

https://www.performancetrucks.net/fo...esults-472581/

good advice right here in my opinion. run the cam and intake if you already have them. id look into the circle d 278mm and some lt headers though. the LTs will take advantage of that cam alot better. who is going to be doing the tuning?

You know I was thinkng of the same thing with the weight issue, I have rcsb, that in my opinion not a heavy truck. But it still is a truck, I didn't want to slander anyone's knowledge as I am a noob as well. So I will run what I have and then just get that circle d tc, and post my times and dyno sheet. Zero you have one bad ass setup, even though everyone is against the cam and intake.

@zero2sixt- in your build you have an lq9, I have the lq4 with dished pistons and 243 heads that will probably give me a cr of 10.5:1 corrdect me if I'm wrong. Does that matter?

The 10.5:1 is a static compression ratio. You also need to consider the dynamic compression ratio when selecting a cam. The bigger the cam, the lower the dcr. And to make it easier, the lower the dcr the less low end.

Like I said earlier, run what you got. The cam is on the small side, but it will still run well. A cam swap is always easier with the engine out of the truck. But it's not that much harder to pull it later if you want to go bigger. Just a few more parts to take off, and a little less elbow room.

Seriously though, hold off until you get some long tubes and a good stall converter. I run a PI and like it. A LOT of people on this site run a circle D and have nothing but good things to say. A 278mm Circle D, like suggested above, runs ~$500.

What size injectors are you going to use?

My friend said my stock injectors off the 5.3 will be fine, I think i am going to breakdown and get the lt for the swap. But the tranny is gonna get done next year jan. I want to get it done at least the engine. As my dad is sick with stage 4 cancer in his liver and I really want him to see and hear, maybe if im lucky ride with me around the block before he as to leave our family.

can we post links on here? I found some lt from pacesetters for $290.

you can post links that are from sponsors, if not its best to keep it to PM's. Also, last i checked the circle d 278mm is 400 shipped. thats what im running and its great.

Good thing I didn't post it, do we get a discount through the sponsors? Has anyone run a used tc, I seen one in here for cheap?

I run 42# injectors. You might be able to get away with something smaller. But stock 5.3s aren't going to be enough. 8.1s might be enough

I run a used converter. Its a crapshoot man. I would only buy a used stall converter if it hasn't been restalled. I know PI and Yank give you a one time free restall.

I have been thinking and like yu said its a crapshoot, and im not that good at craps lol. So I am going to wait and get the right stuff and not take a chance. As far the injectors what brand do you recomend?

The gm 8.1 marine injectors would be what I look for. I never really researched any. I bought mine from my friend who helped me build the truck.

I'd just keep an eye out for some in the classifieds.

I know that now I will use my 102mm intake but at a vise on which tb to use. Would there be to a disadvantage to useing the full 102mm tb our should I just get the 92mm to stay on the safe side?

I sent you a pm.

Speak of the devil. These got your name all over them

LS1TECH

Gonna get them, hopefully there not gone.

Update on build.
 

This is an update of the build. Couple of pics of the short block, with one cylinder head, and a ruff cut on the heads. :cheers: This baby goes in on the 10th of next month. I'm running it with the stock intake and tb for now.


Damn this freaking pics are not showing I dont know what to do. Guess im gonna try pb and see if it works.

there you go man

DAMN!! thanks bro, What did you use?

photobucket, ive got the app on my phone and it uploads them within seconds of me saving them and then just the link button above...it took a while for me to figure it out when i first joined

I'ma check it out.

Nice build, great cause!

Thanks Whitechevy3

HI..N/ALS1, I'm a crazy old fat guy that went crazy with a LQ9 It's in a 2006 GMC Sierra. I was driving it as my daily driver and then decided to go a step farther, open headers,etc. Any way here is what I did.
408 stroker .040 with 11 to 1 diamond pistons. The cam was a comp 224/? and 581/588 lift. I sent it out and had it reground to 238/248 dur and 595/612 lift. It was alot of fun on the street and was no problem. I have a 2800 stall and I wish it would have been a 3600. ( Circle D is the way.) My truck and me wieghed 4280.(without exhaust and a few other extractions.)LOL I've got a turbo 350 for a trans and 4.10's in the back. Oh Yea... It's Carbed. But that ended up being very costly. Cause I deleted the computer also. Your EFI and computer is just fine. Just what ever you go with get a good tune. Pitman or Skeet can give you some great advice there or about any of the guys on here. Remeber ask lots of questions before you jump. It will save you some money. Look at other builds and ask more questions. It's never ending, but alot of fun.
So far I've run 11.80's @ 113 and haven't really got to use the juice yet. Tried a 100 shot but broke the limited slip.Now have a TruTrac. Can't wait for warmer weather. Good luck and My prayers for your dad.

Appreciate it man, Thanks not many poeple have read the part of my dad between 4 forums and the same post. But I cant wait to see what it does, if I still not satisfied with the came I will get it reground. But from damn near stock 5.3 to a .030 bored 6.0 I think I will be plenty satisfied for now. Also I am saving for a 67 Nova, but might have a deal on a true 66 SS Chevy II. The guy doesnt want to sell it but, I think I can twist his arm with some benjamins. Again Thanks from the bottom of my heart.
