yes and yes. there is way more thenone thing holding you back here. not going to point a finger. but i thought the heads would help alot more then they did. I alot of guys make close to your numbers around here cam only G5x4 A4 with pacesetter headers tsp junk y pipe and fast 92 made 424 with out all the go fast cool parts that you have. and this week at the track ran 120 mph but a crap 60 foot so that provs its strong.
if i was you ARH and a nice y pipe with a nice merge would be going on the carthen if it did really gain any more then time to do more home work or trickflows lol not to say your heads are not working just going with what works and has the numbers to show they work

I love the sound from this exhaust and honestly even in the pursuit of numbers I wouldn't trade the sound. However, the headers might be the change I am looking for. Either way, the car is still on the dyno and he is going to make one run with the converter locked so we can see the real power. I still think that this setup will perform quite well, but I never expected these heads to outperform the tried and true sets like the AFR 205's and such. I just wanted to give them a fair shot, and just go with something different.

I can see the point on the headers, but just to confirm that you are thinking of the right exhaust setup that I am running. Here is the link: http://www.texas-speed.com/shop/item...d=196&catid=56

Agreed! I will probably pony up the dough for a better set of headers and see where that gets me. I am still waiting to see how the last tune goes today, and who knows, maybe more power is there in tuning. Either way I still have a bad *** car to enjoy when I get back from Iraq, and the guys at New Era have my respect and my appreciation. We'll see! 
I understand your point. But ask studdern next time your at era what he gained from a y. and i have put three exhaust system in search of sound and power. all were a waste of time and money. I am looking for a stock cat back now to put back on the car and just run a cut out. my last exhaust like yours i gained 20hp and 12tq at the wheels with running a cutout and good y. you can make good power with the setup its just hp here and there your leaving on the table.

like I said before I would have like to see this setup be in the 480rwhp range...I know I have seen numerous dynos from new era and they are very much in line with others...cam only cars putting down 420s with ls6 intake and streetsweeper car, studderin's car is around that too 430-440 ish cam only...
get a good header with a nice y pipe merge like flowmaster and have a very freeflowing catback or cutout like rob and I and the power will pick up...

I dont know for sure on the headers. I got 1 7/8 when I was bolt ons and just had them sence. Im sure mike knows what the gains are over pacesetters. But I would think some lower airbox ducts would be a bigger gain. I didnt see under the lid, but don't think its open, (the free ram air) with just the stock slot in the front.

if you dont have ac the non ac version will fit with a 24gvw trans cooler on the radiator just fine...
If you have ac, no real bottom breathing ram air with fit with the cooler infront of the condensor...but like most do including me, is mount it dope style...it works exactly the same there as it does on the radiator...i monitored my temps and they were exactly the same range in either spot...
search dope mount in the automatic section...

WTF? I'm absolutely miffed at your results.
The below thread has stock (243) heads/ (LS6) intake/ with a baby (222/226 115LSA) cam and headers swap.
Seems your part combination is correct just not as well matched as EPS.

IMO your cam doesn't match your intake/heads. You have heads/intake that will feed a 427 and only have 346 cubic inches. Torque is going to be lazy.
I think you've got some mismatched parts. Put a 90mm throttle body and dump those heads for 215s and I think it would perform better with a F14.
If you want to leave it as is, IDK TREX maybe to get any numbers. Who directed you to put a FAST 102 and 227 heads on a 346 with a mild cam???????

im not a big fan of the f14 high lift or f13 high lift. From what i have seen the regular lift f13/14 perform better. The regular lift versions are awsome though. I have the 14 in my 6.o liter lq4 and had the 13 in my ls1 in my Trans am. both perform great

In all honesty I was expecting higher numbers but the dyno doesnt mean **** its all about how it runs down the track. I'm running almost your setup but with the MS4. I went with 227's as directed by TSP since I have plans for spray. I think these heads are very well matched with the MS4 also. I'm also running a 92mm intake though so I am hoping for around 480 with a 6spd. Hopefully to the dyno soon

Up grading your headers will only get you 4-8 HP over your current set up. I too think that your are little large with your intake and TB. I am heads/cam and bolt ons with a ported stock TB and a Z06 intake making 452/418 with what many folks would call custom grind baby cam. Of course I am running a 6 speed manual trans. That auto will kill your big dyno numbers but the true test is going to be your MPH at the track. Low ets are nice but there are many factors that contribute to a low ET with the driver, suspension, tires atmospheric condition, ect, ect. Your MPH will tell you how much muscle your are making. Good luck with your car and THANK YOU FOR YOUR SERVICE TO OUR COUNTRY!! ...

everyone that says a 102/102 is too big for a 346 has no idea what they are talking about...100% wrong... 
the 102 is not the problem...from the graphs I have seen the prc215s always seem to outperform the prc227s on a 346...
also I have yet to see a prc break 500rwhp, they have been out for 3 years now right? anyone have a graph of one doing this on a 346, sbe...I have seen one do 480rwhp m6...So I am confused why TSP says they are the best aftermarket head on the market....
Dont get me wrong they seem like good heads, but claiming the best out there is a huge statement...I know of another prc 215, 102 fast, m6, trex car with full bolt ons that only put down 463rwhp on the same dyno I did 520rwhp, a4...

I think the heads are probably the main culprit.

Although the heads are a bit large for a 346 they are not too big that it will make it a dog. The tfs 215 and 220 cast measure out to 227 as well. It is probably the port shape or design that makes it make less power than the proven performers like trickflows or afrs. I still dont understand why people dont buy Mast heads and call it a day 11 degree heads and one of the best cylinder head designers. I would also like to wonder what the true cc of the runner is. they might advertise 227 but it could be 230 plus.

so I agree a 92/102 Tb will give the same results if the lid or intake track is not custom to support the bigger size...but the 102 manifold is not to large by any means...
these heads seem to be hyped up without the results to support...

Is that normal for that cam to peak at 6650? I don't know much about the Fxx cams, is there some other good setups with them that you liked Sean? I dont now the auto/stall rpm drop but a setup that you shift at 6800 and keep and keep it close to over 6K is can run good. Maybe have to rev if higher then that to get then best numbers?
