I am new to the whole Mustang thing..but I think your way low..Heads, cams, manifold, and if it is tuned...I would throw the car away if it only made 320rwhp after all that stuff..I mean if my car is making 280rwhp when it was bone stock and the 10 isnt making that much more then 05-09 then only gaining 40hp with that much work..I would think the heads alone would get you about that..then the new mainfold, cams..I would expect in the range of 370whp with that much stuff.

I dont have the dyno sheet yet..its still on the PC at the shop..I posted the day i did it and the whole story..I got my SCT that day..I took it down stock..they did 2 pulls with it stock and it made 278..then I loaded my tune and then the dyno went haywire and the brain of the dyno died and didnt get it run..so i didnt get any files..they got the dyno fixed on monday and I will be going back this week to have it run with my intake and 93 Tune and I will go the stock pull printout as well. I might go see them tomorrow

damn, where they revving the motor to 6900 rpm? lulz
jk
I think I made 255whp stock auto/3.31 gears, but felt more like 240whp lol
The stock auto gears were a joke, not to mention the tune...

265 RWHP seems to be the average for the 05-09's but there are some on the hi and low sides. Then again, dyno #'s can be all over the board and can easily vary by 10-20 RWHP from shop to shop. Then there's the corrections, ambient conditions... so many variables that can skew the data.

With that I had 278 so You probably aren't too far off.
However I think people on this thread are both beefing up AND underestimating the gain you would get from this package.
My best guess with this package would probably be about
100hp over the stock setup on the car. Give or take.
Just my stupid guess though.
None of us will know until someone on this site comes forward with the setup and smacks some dyno numbers on us.

"S" just did right at 350 rwhp with longtubes but without the heads. DR instead of HR Cams though.
