What am i lookin at all said and done with a new (stock) 5.0 with GT40 heads, Cobra manifold, headers back exh with high flows and CAI? Wheel HP i guess. thanks! Any dyno reading would be nice too.

From what ive seen on similiar cars you'll probably be in the 260-270 RWHP range. A Trickflow Stage l or a Comp Cams 281H Camshaft would be a great cam for your application and would put you in the 280-290 RWHP.

lol funny guy, but ya would be cool to have one of those programs where you give your make and modle and then your mods and it "dynos" the car and tells you an estimate of were your HP numbers would be and like torque curve and everything. see it on Horse Power TV one time. but ill just go to the dyno... lol

you can down load it..it's called desk top dyno

more that 100 and less than 1000... i know its not to the decimal, but thats all i have right now! sorry man, j/k


i'd say high 200's 270-295, depends on the tune, weather @ dyno, supporting mods and condition of the motor.

So once i get all of that ish done, get it dyno/tuned? what will they tune? this is where i get lost

the only thing they did when I got my car tuned is adjust the MAF, timing and fuel pressure.

Old Motor:
Stock 135K bottom End
Stock Heads
B303 cam with 224 duration at 50 and 520 lift with 1.7 roller rockers
Edelbrock Performer Intake
70mm Throttle Body
75mm MAF Sensor
19lb Injectors

It made 253 RWHP/ 311 RWTQ the first pull.
Then it made 272 RWHP and 331 RWTQ after they adjusted the MAF, timing and fuel pressure.

Dyno tuning is crucial if you want the most horsepower you can get. Although I've seen cars that gain 5 horsepower from a tune and then I've seen cars that gain 100+ horsepower from tune.

Air/Fuel Ratio, Fuel Pressure, Injector Duty Cycle, Timing advance/retard, rpm peak, etc.
