A 102 MIGHT pick up a slight increase but I would never recommend that for a bolt-on LS6. That's bad advice IMHO. For the $ you'd spend on that you could do a cam swap and pick up some real power and et. Then do a FAST after that and really benefit.
Here is an example. Bolt-on LS6 with FAST 102 +10hp, -3tq.

It's a heavy 4 seater v8 vs. a light two seater v8. I guarentee you that if the 5.0 was put against a new ls3 camaro with the same mods the mustang would be faster.
Of course the z06 will have the edge. Has nothing to do with technology. Variable valve timing isn't new tech just because it's finally in the mustang. The car has a good top end and a lot of compression for a factory car with good gearing.
The mustang did really well against a z06, which is a stout car with just bolt ons. Nothing to be ashamed of losing too.

..... Op, what about dig run? Can that be arranged?
I would also look into a vararam intake with a ported tb. I have a blackwing on my coupe and from what i've seen the vararam reighns supreme on the c5s. Next would more than likely be a Callaway honker, Vortex rammer style intakes. Tehy tend to dyno lower but yield better et's and mph. Thoughts anyone?

430whp for a bolt-on LS6 is being very optimistic. Again, a FAST is not going to gain much on a bolt-on LS6. With a ported FAST in the area of ~7whp and most likely lose a little TQ down low. At that minimal power level the LS6 manifold is not that much of a restriction. Besides a FAST 102 setup new cost about $1300!! LOL
Money isn't an object when talking about what a motor can produce with bolt ons... Whether an UD pulley is a PITA to change before a cam or not is irrelevant.
Would I do it? Hell no.
Only the ones that know what they are doing.

There are plenty of cars that have installed FAST and gained everywhere, lost nowhere. I went from an ls6 intake (that the cam was originally specd for) and picked up 14Rwhp with a butchered (literally worst port job I have ever seen along with other issues) 102 intake/92 TB before the tune and stopped the pull at 5900 RPMs due to issues. It gained 8Rwtq. I have zero doubt the gains would have been better just pulling higher as it was still gaining (shifted with the ls6 around 6300).
With a well ported 102, the gains would have been substantially higher, if you saw the port work you would agree.

Now you are comparing a heavy 4 seater V8 to a mid-lite weight (nowadays) V8.
It barely lost, leave it at that. No excuses needed for either of them.

BINGO!!!!
My car was 487 rwhp with bolt ons only and I still had headers/throttlebody plus ported intake needing to be installed for full bolt ons.
Think I coulda hit 515 rwhp bolt ons only.
But nope. Went for a good size cam and while shes 555 rwhp its just a cammed viper. Very little bragging rights.
But man oh man to wax people with 515 rwhp "bolt ons only" just seems much more special.
+ 1 on finishing the boltons on the c5z06 for 415 rwhp

He isn't either if he don't have a Boss intake. He needs it and then rev it to 7800rpms. W=His gains will be about 35whp with it. He also sounded really quite for having headers and full exhaust.
The 5th gear is the mustangs 1:1 gear. Not sure what yours is. He shouldn't have been scared to go to 5th. Either way you was winning. But it is his best gear really.
Yeah, I was definitely surprised. I think if I would have stayed in it longer in 4th, I would have slowly walked. I started to in the 1st video at the very end. But if the race would have went any further he would have been shifting into 5th.
My next race is gonna be my buddy with a 2000 SS. He just did cam, headers, intake and he has 3.73's, M6. He dynoed 390/375. He and the mustang raced, but it was kind of fucked up. The mustang barely got him. I'll be sure to get another video.

Guys the 5.0 is a beast, get over it. They pull to over 7k rpm and the heads flow darn near ls7 territory (325cfm intake). And of course they are four-valve heads. That's why they respond so well to exhaust/ bolt-on mods, cause they like to breathe up top. It' s easy to see why the run so well, technology.
As far as bolt-on ls6 cars go, 95% of the c5z owners on corvetteforum would tell you that the OP's car is indeed a full bolt-on car and that his numbers were extremely high at that, too. Most bolt-on ls6 vettes, (headers, intake, exhaust) dyno from 380-390whp. And not many agree with putting fast intakes on stock cammed cars. I myself was told putting my tpis 90mm and ported ls6 intake on my bolt-on only car would net 7-10 whp tops. It sucks, but it is what it is.

C5Zs get nasty compared to most competitors above 100mph, 4th-5th gear is where I would stay away from a C5Z.

lemons12, you're right about the c5z in these videos, it was starting to walk in 4th, both runs. At least it would've walked the 5.0. 
I forgot to mention that while 400whp in a c5z is possible,not counting light flywheel and clutch, the drive train does rob more hp than an f-body to the wheels. It'd be cool if someone has this info as I've heard/read it before.

Full bolt ons is full bolt ons. Full bolt ons is not a CAI/Full exhaust/tune, there is a lot left to be gained after that.
They also might not agree on putting them on there... That has ZERO to do with the FACT that a FAST 90/92/102 WILL increase performance of the car.
So we have one true full bolt on ls6 in here making what? 430Rwhp? And one that has quite a few bolt ons making 395Rwhp... I mean its 5Rwhp off your "average" dyno numbers.
