KickerStang said:Problem...
1. There are no aftermarket heads, all you can do it port and you might gain 15HP $1300
2. There are no aftermarket intakes except for the bullet and you might gain 5HP $1400
3. You might gain 10HP with cams $500
4. You might gain 2-4HP from shorties over the stock manifolds $500+
On a 5.0 you can bet on doubling those gains
1. 30HP for heads
2. 10HP for intake
3. 10-20HP for cams
4. 10HP for shorties
KickerStang said:What car doesn't? How much do you think a 5.0 would dyno at w/decent heads, cam, intake?
The reason why I say decent is because the stock heads ect are crap as opposed to the PI heads. I think ford did a good job putting these PI heads on our cars, but imagine if they put decent heads ect on the 5.0s.

Reichards intake manifold is bad.. with a blower even badder.
Very good article about it (Aug 03 5.0 Mustang pg 141)
Roxanne Shepards car gained 85.3hp and 68.9 ft/lbs of torque with the livernois cams. (Sept.03 5.0 Mustang, pg 135)

Yeah ! What he said !
But what is the deal on these heads, cams, and intake ?! That's amazing. Whay haven't we heard more on all that. I only have heard very little on the Reichard intake that I thought wasn't really available ?
Guess I'm gettin' that mag. !
KickerStang said:68-People are having a very hard time gaining 30HP on P&P alone, that is usually with cams. 500RWHP is not too shabby, but you have to forge the whole motor to sustain that kind of power, not just as easy as correcting internal mods, you are talking whole new engine. Why not start right with more displacement. I am disappointed in you. Of all people you should be defending the 302. And I think you could put down more than 500+RWHP with a 5.0 with same mods dont you?
68 & 00 GT said:Ha good call ! Sorry to disappoint you - you're right my 68 does have a 302 ! I kinda feel bad now. Not - anyway my 4.6 will stomp a mud hole in my 302 though, and it's not exactly stock either. Yes I think both combos can produce 500 RWHP, but by the time you go through the whole hassle to buy, and build a whole new 5.0 to do so, and get it in there it seems to build an already existing 4.6 to do the same will be cheaper, and easier.

Sorry Dale but....
You call that almost stock !
Wish my 13.5 @ 102mph 4.6 was "almost stock"
Dale Royster said:My 4.6 car is almost in the 12 second range and its almost stock really. Ive done a few bolt ons and the blower. I have stock tires and stock gear. My a/c works perfectly, and Ive lightened it up some, but it still retains full functionality. Ill drive my car to Florida, California or anywhere else for that matter tomorrow! Can you do that with a 12 second 5.0 car? My 87 GT was a turd compared to my 01 GT. Give it time, mods are the future. The 302 is dead.

The heads make sense now that I think about it, they are probably upgrade heads for a 96-98 Motor. But as far as the cams, her engine isnt a stroker its .020 overbore thats it. Shes got forged internals pretty much and a few other things. An 85 hp gain for 500 bucks is pretty fair trade if you ask me!! I follow the livernois stuff pretty close because its on my streetAccording to the article about the intake, they are available in limited quantities right now if I remember right. (Its a couple months old)
KickerStang said:Your car is not even close to stock! I am almost in the 12 second range WITHOUT a blower!
KickerStang said:You can have a 5.0 w/AC, lightened up some, and drive it across country, slap a blower on it and hit 12's no problem. What is your point?
KickerStang said:Hell, you could do it NA if you just get gears, h/c/i and good driving. You dont even need that much. My buddy has a 91Notch with just LTs, o/r h pipe, catback, pullies, timing bumped, CAI, and he hits high 12's. Yes, he has the A/C and smog eliminated, but the point is you can do it even more so with a blower and a/c, smog, ect.
KickerStang said:GT black, can you give me some reference material to prove this. I dont think the Cobra and GT block are the same, and you cant just swap cobra heads and intakes otherwise every GT looking for more power would have done this already. If it is true, why are people scrambling to get their hands on a Cobra crate motor for $3100?
Dale-Those are PI heads, not aftermarket heads. That 40HP is over a stock head on a 96-98GT not a 99-03GT. The Reichard Racing intake is great on blown cars, not on NA. People are losing low end TQ and not gaining HP on NA applications. What else did Livernois have on that car hmmm? Definately not NA and if I remember correctly it was on a stroked 4.6. You are correct shorties are a waste on the 2V LTs are the way to go, but if you ask me LTs are the way to go on the 5.0s too.

Dale Royster said:Its never been apart, Its got bigger injectors, bigger mass air and different spark plugs to support the blower. Its never been apart, nothing is ported, stock manifolds.. My car has bolt ons and a blower!
You just made my point, your car goes almost 12s WITHOUT all this other crap that makes your car a pain in the *$$ to drive every day!!!!
I dont have all that stuff and Ive got a convertible to boot!
GTBlack_00 said:Do your research, you'll find that all blocks and heads are compatible. Cranks are not though, you would however have to modify the timing chain guides to use 4v heads on an orig 2v block. Most people dont switch heads because the 2v is kinda cool to most people and makes more torque in the lower rpm range.
PS Dale, get some DR's or something you should be very low 12's if not better.
