If the PI headswapped car was slow, then it wasn't running right. These motors have 10:5 compression because the pistons are flatter topped than the 99+ creating more compression.
5.0 vs 4.6
- Thread starter bullet 1
- Start date
Everybody is going to tell you to get what they own cause they like what they drive.
The 5.0s are cheaper to mod.(like everybody said)
The 96-98 cost alittle more then the 5.0s to mod.(they can all be fast very easy).
The guy that ran 14.2-14.4-14.5 with an 03GT, What was your 60' & trap (thats slow brutha) I ran with a k&n on a stock auto 14.2 @ 99.
They are all easy and pretty cheap to mod & make fast. It all depends on where you want to start and what you want to do with it in the future.

Also if your going to just do light mods, Don't forget to get a gear that will wake up any 5.0 or 4.6L.
If you do like a CAI, MAF, T/B & full Exhaust like I said do the GEAR & DRs. For now you will be happy w/ that set-up.(light mods).

Yep, it was pretty slow. And as far as I know, it was running right. He hadn't mentioned any problems to me. My girlfriends LT-1 felt like it was a lot faster. And all it has is pulleys and 4.10's.
Not everyone lol, I told him to get something I don't own. :thumbsup:
Wow that sucks. I would have been mad if did all that work and there wasn't much improvement. I gained about 60rwhp with my swap. But the best part is it pulls strong all the way to 6000rpm unlike when stock when it dropped off after 4200. Looking at my graphs i actually gained almost 100!RWHP!!) at 6000rpm!!:beer:
I'm sure it was an improvement over the stock heads, I dunno, but after seeing all the money and work he put in to the car, I wasn't impressed.
I hope you are not talking about the 98 GT you have in your profile. If you are I am calling Bull Shit. The 96-98 GTs could barely beat a V6 scumaro so please dont tell me you have some kind of special edition or some such shit. Hell the Cobra in 98 was only putting down about 271 bone stock (RWHP). Not rying to flame ya but there is no friggin way.;-)
Okay, here's my dyno sheet from before the head work.
As far as 5.0 being better than a 4.6 ,the only way is the aftermarket(and i have owned both) .Power wise a bolt on gt esp the newer ones can do 270+ with no internal mods and run low 12's all day long with the right driver.
modulars dont split blocks when making good power.
mod cars love blowers better.
96~98 arent worth having unless they have at least a headswap.
The average 5.0 will eat it alive.
Dont get me wrong i love the 5.0 to.But ,you dont see many 5.0s putting down 500+ and getting 20+ mpg on the highway :coolman: on stock blocks.
But it boils down to money in either car.Speed cost money how fast do you want to go :burnout:

Is that 206 RWHP and 266 RWTQ?
Yes. I had exhaust but that doesn't give you too much, especially torque.
If you want to see the post swap dyno when I put down 262/294 click here.... http://www.svtperformance.com/video/dyno_tune/joel3.mpg
4.6's dont put out shit for torque. it's a proven fact.
Good lord get a clue guy. Stock vs Stock a 4.6 puts more torque down than a 5.0, just a little later in the power band. :rollseyes

stock for stock it the 4.6 puts down like 5 more lbs/ft or torque then the 5.0. how many naturally aspirated 4.6's, no juice or anything do you see putting out 425 flywheel horsepower? that's all i have to say. it can't be done. at least not yet, maybe years from now. mustangs and fast fords i believe are the ones who got 427hp out of a naturally aspirated 302.

I've never raced one actually. I put more power down than a stock one, but obviously NOBODY leaves their stangs stock anyway. Thanks..:beer:
A stock 99+GT is nothing special. My speed density 87' w/ 3.73's and cold air could beat those off the line. But, at about 70mph the GT would start to catch up and eventually pass me.
Now a 96-98' w/o PI heads, my car bone stock had no problems with them at any area on the speedo.

Well my little 01 GT that makes no TQ or HP ran 13.62 with only a CAI. It put down 244 RWHP and 287 RWTQ in that trim also. No you want see any 4.6's making 425 on the motor. Then again you won't see that from 302 cubic inches either, not streetable power anyway. All out race engine sure.
It will end up being a preference thing. You can make anything fast with enough money. Chances are no matter which one you buy, you'll keep modding it for a while. It's adictive once you get started. I suggest driving good example of both in stock form and go from there.:beer:

Stock sheet and slip
This dyno is a straight off the street onto the rollers pair of runs also. ;-):beer:
