those numbers are sooo good they're too good to be true. I'm just going to say it, and I mean absolutely no offense to you whatsoever but more to the operator of the dynoand again seriously, I'm not trying to offend you so please don't think I'm attacking you.
You either have the strongest mustang I've ever seen, and by a large margin... or something is fishy there. Those numbers are just not in line man.. I'm curious to see what others are going to say that have had exposure to alot of cars with mods like that.

WHAT?!?!?
those number are actually not great for a TFS headed car with stage 2 cams, My NPI! headed 4.6 made 330/306, 11 less rwhp and 1 less ftlb! with NPI heads!!!!
ive seen a few local guy making over 375rwhp and running mid 11's with TFS heads
Out here where I run in CA those numbers are unheard of. You just don't see numbers like that. A Longtube, cammed, head, supporting mod 4.6 is usually in the 300-310 range. To even suggest 375 is insane. I mean come on, no way on gods green earth. The guy must have swapped an ls in there or soething
furthermore 340 is so far away from everything I've seen firsthand that it sounds absurd to me, although not to say it's not possible, though from my experience I would say it highly unlikelyand to what the op said about the numbers being the numbers....that's not true. Those things can be distorted in many ways, if that guy wanted to boost your numbers or reduce them he could easily accomplish that on a given run. But again, I'm
hey sick2v, i beleive it. theres always someone in disbeleif about hp gains, but the tfs heads are almost getting ready to out win the FI route. you get H/Cs for less then $3k and makes as much if not more then a s/c at 9psi. with that said, does that mean you can produce more then 400hp going n/a and not worry about the bottom end grenading form the added boost pressure??? thats an interesting fact id like to know.
what???? what about the supporting mods? What power you think your going to make without them?
heads assembled $1750
Cams $600
Head Gaskets $100
Headers $500
PP TB and Plenum $200
Tuner $350
H pipe $250
Exhaust$500
Long tubes $500
Tune$400
Not to mention Most anyone can put on a supercharger but what about these parts? 95% will pay for the Header install, Head install, and degree the cams. So add another $1000 for that, if not more with the degree
TOTAL $6250
and your comparing that to a base supercharger kit for 3g's that needs none of those supporting mods to make that power? How exactly do you consider that getting ready to outwin.
Maybe I'm wrong here folks. But I've seen lots of stangs....And lots on the dyno. Not just my car or some buddies car. That number is considerably higher than I've ever seen in person. And to suggest that someone did 375rwhp with a bolt ons is funny. That's simply not going to happen. Your not going to take a patriot car like mine, fox lake, or whatever heads you may have and add 35-60 MORE hp just by swapping to them. Simply not going to happen.
In cases like the OP who put down way more power than I've personally ever seen on a simlair modded car I can only say that the chances are higher we have something dyno / operator related to those numbers than the chance that this car is a complete freak defying anything else I've ever seen by such a large margin.
Besides.....Post back up with a track time and then we'll know the real story, I'll be interested to hear if you'll track the car. Dyno's can vary greatly, track times don't lie

Wow, its almost like you just refuse to believe......even with proof posted in front of your face. Good flowing heads/cams really wake up 2V 4.6 motors and so far, TrickFlow has designed the best set of heads on the market. There has been a LOT of talk about these TFS heads for a long time and for precisely this reason. For example, scupking made over 310rwhp with stock heads. Is it THAT hard to believe that a pair of good-flowing heads would add another 30rwhp or more?
Aftermarket heads on an LSx engine can add as much as 50+rwhp to a lightly/moderately modded car, so why cant a pair of 4.6 heads do something similar?
BTW, the prices you're listing for mods are ridiculous
