Hey, guy you were keeping this from checking in here. 
Congrats on the numbers. My numbers are actually 400/367, 405 was before the tune and drivetrain stuff. Were those SAE numbers Alfred gave you? The weight thing is going to make a big difference between us, but I'd still like to get together and run em sometime soon when you get your clutch issue sorted out. I'm always ready to go, and I'm pretty sure I can hold my own in this grudge match.
With those numbers, you should be able to hold pretty well against me even with the weight difference, but my gearing is going to make a big difference from a dig, as well.
And fuel system is one of the next things I was looking into on my car. I want to have someone take a look at the duty cycle. I've been saying from the beginning that it may very well be one of the reasons my car just isn't putting out the power it's supposed to. I think it could be your problem, as well, but I would absolutely swap in an 85mm MAF next. I've done a lot of reading on the subject and I really think you're holding yourself back with that stock MAF.

Yeah, he's got stock heads and he's also running through a 3" Steel driveshaft and a 12-bolt with 4.10s, so it's definitely not a dyno queen. It's fairly mild cam, as well, so I wouldn't have expected much higher numbers. A cam only putting down almost 400 to the wheels with stock heads and a very heavy drivetrain is impressive.

All things considered I am pretty happy. Actually I couldnt post about this for a while. I had a grudge w/ a local kid who didnt even know I did the swap.
A quick run down of the mods.
Vengence Racing VRx4 Cam 228/230 .588/.592 112
Ported 90/90 by Vengence, Sanded and Painted
SLP Flow Pack (no smooth bellow)
SLP U/D pulley
Dynatech SuperMaxx Headers w/ emission w/ CATS
Corsa Cat back
Textralia oz-700 Z-grip
Moser 12 Bolt w/ 4.10's
3" Steel DS
Stock Heads, Waterpump, Rockers, Injectors, and Fuel Pump, Dyno Tuned.
A quick Run down on past dyno's
Stock w/ Lid, m6, 10 bolt:
324 RWHP @ 5,300 rpms
346.7 RWTQ @ 4,450 rpms
Lid, 12 bolt, DS, Headers, Cat back, bolt on dyno tune:
UN-Corrected:
1st pull: 336.6 RWHP @ 5,500 rpms;
5th pull: 350.6 RWHP @ 5,500 rpms;
1st pull: 355.0 RWTQ @ 4,500 rpms;
5th pull: 361.8 RWTQ @ 4,500 rpms;
Corrected:
1st pull: 326.8 RWHP @ 5,500 rpms;
5th pull: 339.9 RWHP @ 5,500 rpms;
1st pull: 344.7 RWTQ @ 4,500 rpms;
5th pull: 350.8 RWTQ @ 4,500 rpms;
Cam/Intake/UD pulley Swap:
396 RWHP @ 6,200
375 RWTQ @ 4,500
TQ was over 350 @ 3,500
This was with a retune which didnt do much over the bolt on tune, minor clean up. Dirty air filter and fuel filter and heavier drive line
Had it been a stocker drive line, it wouldnt be un reasonable that it would 412-415 rwhp on a MILD cam that drives like stock, and has a nice, exotic sound w/ the cat back.
Since I've gotten over Cancer, now I will get a chance to make it to the track. The thing weighs with me just short of 3900lbs. I dont expect 11's but 12.20's isnt out of the question.
As for the ported 90, I am sure it helped a little but when paired with ported heads it should do 430-440 rwhp, maybe 5.3L 225cc or Ported LS6, I havent decided.
Oh and with the kid who I was keeping this from, he made 405 RWHP with a similar (maybe a lil smaller cam and ported Patriot LS6 heads), At the peak he edged me but below 5.5k I owned him in the power dept.
