What should I expect from new setup?

[94GTMustang5.0]

I recently tore down my 89 LX to change the headgaskets, and while i have the heads off i have decided to go the GT40P route. Here is all of the changes i am making.

- E7 heads changed to freshly machined GT40p's, no porting.
- Stock intake manifolds to Ford Racing Cobra (GT40) manifolds.
- BBK equal length headers changed to Ford Racing GT40P specific shorties
- 3g ALT upgrade
- clutch fan changed out for electric fan

What should I expect for RWHP? The other mods to the car are listed in my sig, just a RAI, full exhaust and the mods above.

250-275 hp prob.. I have similar mods.I got 252hp not runnng right.

 

[Cobra1741]

my cobra runs gt40s unported, with cobra intake and e303 and put down 270-275 rwhp, and 300-305 ft/lbs. so id say like above between 245 to 260 hp. but what really matters are the time slips =)
