FFHP 408 dino numbers i dyno'd my FFHP 408 M6 last weekend in michigan by wheel to wheel powertrain i expected at least 500 hp i told my buddy anything over would be a gift-quess what santa came early -my final numbers 511 RWHP & 468 RWTQ 
the 1st pull was 455 RWHP with the mail order tune. i almost cried
i was having a cold idle problem - so i went the night before dropped off the car took a taxi to the motel & came back in the morning. W2W said we only had a small window of time to tweak the cold idle. he fixed it
the car runs totally different the 408 is a real animal
my modifications are
FFHP long block=11 :1
TSP texas giant cam
stock ls6 intake
stock throttle body

Wow! Good #'s all that with a stock intake setup and the 11.1 comp ratio isn't all that high compared to some others out there. Congrats, it should be wicked when you do a 90/90 intake on it.

Sweet! 
the heads are FFHP Stage 3 6.0 heads if I remember right, Brad will know the full specs and I am sure Hungarian will chime in.
I was pleased to hear your results Laslo especially considering what you had been through before you contacted us.
Get a FAST 90/90 and you should see a few more HP

its a 6 speed - with the mail order tune the car ran very jerky at low speeds

after w2w did the tune it is night & day different - close to perfect
w2w's dyno is quite stingy compared to other dynos as well...they do a lot of stuff for GM and it needs to be very accurate so they said most people will get higher numbers on other people's mustang dynos compared to theirs...
