Let me get this straight..
Everyone here would rather spend thousands of dollars on another new set of heads and cam and ECU tune and do all that work again and have their car off the road again and have a guy thrash their car on a dyno again and risk engine damage while dyno-ing it or while installing the new heads/cam... to hopefully increase their trap speed by 6mph
instead of experimenting with their tyre pressure, tyre heat and launch RPM's - making their car more efficient (for free) to gain a whopping 0.9 seconds in the 1/4 mile?
Confused @ level of ignorance and ego
Not sure if real life.
"Nah it's not my driving or how much psi I put in my tyres or my burnout duration, it's da car bro. Just need to spend more money on it"
Made me think of this at 0:33
lol
You'd probably get the same results (as you would with the new heads and cam you're planning on buying) with a vent or 2 mounted on your hood over your radiator-to-engine gap.

If your goal is just plain power or MPH, well, you have the forgies, spray more nitrous. I usually recommend the turbocharger but since you already selected an 11:1 you have limited headroom. I suppose you could do with E85 but seriously, I would have gone 10:1 turbo before 11:1 nitrous build. I am curious what sort of head gasket you have... hmm

There's no magical thing you can do to make a bad combo all of a sudden be good, and no amount of tire pressure, heat and launch technique is going to make up for that. And yeah, I sure believe that a simple tire pressure change is going to net you a full second improvement at the drag strip. Dream on buddy.
Dude, the "trap" isn't disappointing. The TIME is. Who gives a crap about the quarter mile top speed (apart from you)??????? Also, it's fine/fast.
When people ask you "what does your car do on the quarter" you don't answer back "xxx mph". You tell them the time.
Very strange.
"Any" car, any motor... 11.6 is a slow time for a 122mph trap.
He should be in the 10's (with slicks).
Like I said, my old mates ran high 10's with slower top speeds (with different engines, not LS1's) and have noticed hundreds of other cars running very similar times and mph to them.
His main problem is his launch.
Like I also said; if he cut his 60 ft time by just 0.1 of a second, he will be in the 10's. Almost a second improvement in the quarter.
He should experiment with tyre pressures, heat and engine RPM when launching and not put the blame on his engine/setup.
Don't know how anyone can even slightly disagree with what I'm saying.

ummm well add me to the list that is concerned with trap speeds because that is an indicator of the power you are making. The et is more of how you are putting the power down that you have. You telling him to heat up the tires more. For what? If he is hooking he is hooking.
Why are people saying the a/f is off? Well IT IS! The cam is very small for that size motor as well.

Before blindly spending money and throwing parts at it, I would get the tune dialed in.
What does your power curve look like? What are your shift points? What is the suspension set-up? There are more factors than just "motor" when it comes to going down the 1/4.

I ran 11.6@116 mph on a 1.72 60ft with a 390rwhp ls1 346ci combo.
Something is severely screwed up with your runs to start with, the number don't add up at all. Judging by your 1/8th mile time (which still isn't that good) the problem gets worse on the backhalf than the front. When I ran 11.6 my 1/8th mile was a 7.45.
Past that your AFR is horrible if your reading is accurate which leads me to believe the tune in general is probably bad. For what it's worth when I leaned mine out from 11.8-12.0:1 down to 12.8:1 I gained just over a tenth and MPH in the 1/4. You would likely gain more than that and who knows if your timing table sucks as bad as the fueling does.
You have a lot left in what you already have if you line out all the problems you mentioned. I would start there instead of throwing more parts at it and it still running like **** because you haven't spent the time to go through everything.

When you make a mistake and put together a mis-matched combo that underperforms then yes, you HAVE to spend money and do the work again to make it work.

HE ALREADY HAS A LOT OF POWER. HIS 122MPH TRAP PROVES THAT.
HIS POWER (OR HEADS/CAM) ISN'T THE ISSUE. HIS LAUNCH IS.
SURE, HE WILL GAIN MORE POWER AND INCREASE HIS TRAP SPEED BY A BIT WITH OTHER HEADS AND CAM. BIG DEAL. AGAIN, HIS PROBLEM ISN'T LACK OF POWER.
OTHER CARS OF SIMILAR SIZE AND WEIGHT WITH 122MPH TRAPS ARE COMFORTABLY IN THE 10's.
YES, IF HE IMPROVES HIS LAUNCH BY JUST 0.1 OF A SECOND THEN HE WILL IMPROVE HIS QUARTER MILE TIME BY 0.9 OF A SECOND.
ANY ONLINE QUARTER MILE CALCULATOR WILL TELL YOU THAT.
THE QUARTER MILE IS ALL ABOUT ACCELERATION, NOT TOP SPEED YOU IGNORANT FOOL(s).
WHEN EXTREMELY QUICK CARS "SWITCH OFF" HALF WAY DOWN THE TRACK DUE TO A PROBLEM, THEY STILL PULL CRAZY QUICK TIMES.
"There's no magical thing you can do to make a bad combo all of a sudden be good, and no amount of tire pressure, heat and launch technique is going to make up for that."
SO IF YOU SAW A GUY FRYING HIS TYRES, 1ST, 2ND, 3RD GEAR ALL UP THE DRAG STRIP AND HE TOLD YOU HE WAS DISAPPOINTED WITH HIS 17 SECOND TIME, WOULD YOU ALSO THINK AND TELL HIM THAT HE NEEDS MORE POWER AND TELL ME TO "dream on" WHEN I TELL HIM HE NEEDS TO STOP WHEEL SPINNING AND THAT HE'LL IMPROVE HIS TIME BY DOING SO?

do the math, fools.
Something's wrong.. and it ain't the heads and cam.

As far as the tune the tuner gave it a base tune because the transmission was shifting through the gears immediately cruising and said the converter felt extremely loose. After that i spent some time on the street tweaking part throttle shift points and it drove pretty well and thats when i made some track passes. I then returned to him and on the dyno he selected manual third and whenever he made a pull i guess it let go. It ramped up to around 250 rwhp and pegged the limiter. Not sure if it was converter or trans but I have a brand new jakes performance level 3 4L80E with transbrake and a PTC nitrous converter to go in. Timing is around 25 degrees WOT and and knock sensors were pulling up to 8 degrees around 5000 rpm which i assume is false knock i have not determined that yet.

I don't appreciate getting "dream on buddy" comments after giving people great advice, while they give people crap advice.

That isn't my "main reasoning".
Common sense + seeing over 100 10-second cars with slower trap speeds is.
Keep trying.

All I said is that for his parts the times are not bad...not once did I say to go get new heads and cam. But yeah, you're the only one giving the great advice in this thread while we all are giving him crap advice. Maybe the whole car world should just stop doing what they've been doing and pull up a chair to listen to the great all knowledgeable one that just joined this month and can't even figure out how to correctly use a scanner and monitor his voltage.

Look, if his 60 foot was abysmal, like 2.0 and he was running mid 11s I can see how improving the launch will get him a 10 second car. If you think that by going from 1.6 to 1.5 60 foot is all that he has to do to go from 11.6 to 10.7 then you are indeed dreaming.

I'm sure it's wrong and silly.
