You don't know plenty with an LS. If you did you wouldn't be stuck at still slower than what unopened 5.7 ls1 cars have 1/4 mile'd at your raceweight. Go back to the sbc if it worked for you. And i'm not being arrogant i'm being real, the LS just isn't for some people that don't understand it. If you had a sbc and it was working, go back to it.
The carb isn't going to magically pick that car up a whole 1 second in the 1/4 mile, which is where it should be. And i will still never run a #7 spark plug in a pump gas n/a ls. I have tr55 plugs in my 11:1cr ls2, runs like a champ, lots of timing, no detonation.
Maybe it's just me but i NEVER saw someone run colder than 5 plugs in a n/a pump gas 5.7 and 6.0 that et'd well.
Your car sounds flat even on the idle vids. There's definitely something off with the combo and it's probably a combination of things. It wouldn't even surprise me to swap your parts over to a good condition stock bottom end 6.0 straight from how GM made it, and it runs better.
What about the crank, was the crank messed with? the reluctor wheel wasn't changed/swapped over by any chance?
I don't like to mess with what GM made, the least as possible. My ls2 short motor when i bought it was a 58x reluctor and the entire short motor it was like new condition even the bearings. My ECU is 24x, and rather than me trust someone to swap over the reluctor wheel, i found a perfect low mile 24x crank and used that instead. Why? because i thought there's a chance if i get a so called "professional" to swap reluctor they might fit it wrong and the whole timing is out of wack. I also reused the gm original main bearings. Why? because they're also better than aftermarket.
Same goes for the cylinder walls. Did i bore my ls2 .005 like most of the sheep do because for whatever reason they're brainwashed you need a fresh bore/hone to make power? nope..I left it standard bore. GM bore and final hone is rounder and more true than what most machine shops will do. We're not dealing with 1970's cast iron engines here that are so old they need full machine shop work.
There's a reason so many
SBE ls cars, are so fast. Mine seems to run hard with JE fsr pistons but again i left it standard bore.
What about the converter? it could be no good for the combination. Some people have tried 5 different converters before they get it right. I wanted a new 8" converter for my ls2 and i bought an 8" spragless converter used out of a car that had run an 8.9 second 1/4, n/a, engine dynoed 800hp. The converter was already proven to me that it's efficient enough to ET what it should ET, so i bought it knowing it is going to work and just stall a little less in my car because i'm making less torque than he had. But i trusted it, because it had already proven that it works well.
The people that just slap parts together and expect things to 1/4 mile like the good cars do, it doesn't always work out that way. And who are all these cam companies we've never seen run a quick n/a et in an LS? Back in the 2000's when n/a LS records were broken that still haven't been beaten.... there were FUTRAL (cam motion), THUNDER RACING (comp cams), ED CURTIS, LG MOTORSPORTS, probably not many others if any. GrannySSshifting also, his cars ran hard.
Mike does good cams? Where's a quick n/a LS 1/4 mile from one of his cams? I mean in these low 11 - to low 10 and high 9 second n/a LS cars, in the 5.7-6.2 engines. If someone can show me one, then i will say he does good cams.
I bought my custom comp cam 243/250 ( lsl lobes) from a guy with a stock stroke n/a ls3, it dynoed a legit 500rwhp, n/a. He only sold it to go a lot more radical turbo. This cam has a 108 LSA, just like many of the early-mid 2000's n/a LS record holder cams. The valve events are also very similar to the thunder racing t-rex, i think he must have copied it. If this cam hadn't come along when it did, i would have most probably contacted Ed Curtis for a cam. What's with all these 114 lsa LS cams lately and i don't even think i've seen one run a good 1/4 mile? Why are people reinventing the wheel?
Why do we need ongoing jabs of experimental mRNA poisons just to live, because some fuckwit sellout politician paid by a multi-billionaire with vested interests said so? The world has gone mad, n/a LS barely cracking 11's in 2021...... LMFAO. If you weren't on LS1TECH back in the early-mid 2000's to see LS cars run 9's n/a with big bore stock stroke junk... GeorgeC's car, then you had people like TomTheRoofer, Raughammer, Futral Motorsports had 408ci cars cranking out 700hp flywheel back then, Texas Speed running 9's with sbe n/a 5.7's, the list goes on, my own car was slapped together and 3700lb's and it ran 119mph n/a, a 5.7 ls1 in an IRS cambered wheel piece of shit Holden. Why, because the guy that did the heads (Absolute Speed) and the guy that did the cam (Futral Motorsports) knew WTF they were doing. They designed their parts by going to the track every week and testing it at the track to see what worked best. What do most parts sellers do nowdays?.. throw you a flow number or dyno number that looks impressive, and says pay me, i have the results. No you don't, you have numbers on a screen. Take it to the 1/4 mile and see what it does.
If you weren't around back then you might not understand that most of the world (not everyone) has collectively gotten more RETARDED since then, not progressed. A new C8 corvette runs low 11's... ok, ooh wow. Hot rodders did that (and then some) in the 1980's in the backyard with junk 1970s parts. Slapped together 440 mopars ran high 10's with a 509 hydraulic cam 30 years ago. But we're now so much smarter, because the billionaire zionist jew owned TV said so, while he works his hardest behind your back at making you dumber.
Nah buddy, you don't know plenty about the LS. You came on here asking for help because your built 6.0 was running 12's when others with similar parts are running mid 10's. You are trying to copy other LS n/a legends but you just don't know how to get the car to run hard, but they did and do. They are not internet myths. GeorgeC on ls1tech over 15 years ago wasn't an internet myth when his wheelstanding big bore stock stroke junk ran 9.9 1/4 n/a with ported GM cathedral heads and a fucking stock ls6 intake and ported stock TB and STOCK MAF !!!! Neither was Coleman Roddy running low 9's n/a with a 404ci LS. But but 2021... we need 105mm TB's and 420cfm heads with 330cc intake ports and china 4" cranks that flex like fuck under power, just to go 9's. Yeah that's why you also need a vaccine ongoing with booster shots just to live for a flu with a 99.8% survival rate, most of you have been dumbed down so much that the billionaire cabal of Bill Gates, Soros, and the Rothschilds can now rape you completely fucking blind, as opposed to just half.
What about this "internet myth" below .... nah, he had a fucking brain..... and he also used stock GM hydraulic lifters and stock rockers, lmfao at all the "we need $1000 bushed solid roller lifters to run hard n/a people", nope not with an LS you don't, GM gave us all a gift and most of you don't even know how to use it
Coleman, itching to get back into the fast lane purchased a 2002 Camaro Z28, dropped in a fresh 404ci LS2 with LS2 heads backed by a TH350 trans along with some extras and was off to run low 9s. - GM High Tech Performance

A guy i know ran 11.4 1/4's, in a fucking pos holden commodore, 3500lb's, ls1 UNOPENED, Naturally aspirated. Stock cam and stock 241 heads. STOCK!. It happened. A lighter 4th gen, went 10.6's 1/4, n/a UNOPENED, stock cam & heads. I don't want to hear what the idiots at your local track run with n/a LS's these days, because many people have gotten dumber, and that's a fact. Many, but not all. GrannySSshifting who has run 9's in n/a ls3's offered you for you to take your car to him to dyno, so he can figure it out. You've probably spent 3x more that that on parts by now you didn't need, to go 1 tenth faster. Notice he doesn't post on here anymore, why would he bother, it's a lost cause.
