v8 engine swap

a buddy of mine have a 4.6 v8 engine from a ford crown vic cop car would i be able to put in my stang which is a 2000 3.8 v6

Yes.

With a fair amount of work, yep.

yes you can, is it worth it, absolutely not, the crown vics use the NPI heads, so you will gain 10 rwhp or so at the most

for the same price, 4.10 gears, detroit true trac, TA rear girdle in the rear, a higher stall TC, and jmod if its an auto, and get a powerpack HCI kit from supersixmotorsports.com.

the ford 3.8 is far superior to the 4.6, it is an overall stronger motor and the heads stock flow better, there is a ton of potential out there but people think because its only a V6 that its a worthless motor

I would certainly not go as far to say that is a far superior motor. Stock for stock the 4.6 (all trims ever installed in a mustant) put out more power and torque than the 3.8 did. With the same type of work to both motors the 4.6 still has the advantage. I am not calling is crap, but lets be realistic. For the record, i would not bother swaping that crusty old motor either.

the reason the 4.6 has more power is because ford never decided to produce the sn95 stang with a eaton M90 (tbird SC) motor like one of the conecepts, if so, the only stang that would of touched it is the s197 GT,

preformance parts for the 4.6 are also more expensive, and if you want to go into serious work, you need to upgrade the motor at around 450 HP, a stock 3.8 block and crank have been proven to about 800 HP with just forged internals, while the 4.6 may have always had more power stock,there is great potential for the 3.8, see my posts in Matts flow numbers

That is really a useless argument. Pointless to argue a concept car that was never on the market. There is no 3.8 with just forged internals that is running 800 hp. You have to dump some cash into that motor to see impressive results. There is going to be considerable money put into the 3.8 just to reach the performance levels that the stock GT is putting out, and even then you are now comparing a fairly tweaked car against a Stock GT. After your have gained enough (and paid enough) power to accomplish the task of this "monster V6" than there are many other parts on the car that are just not up to the task in stock trim. Anytime someone argues that a motor is a good as another if you change the internals, port the heads, run nitrous, add forced induction or anything else like that, the argument is pretty much crap. I don't think its necessary for me to add any disclaimer about how I am not knocking the V6.

it should take no more then $2500 if you know what your doing to get any v6 split port or single port into the high 13s/low 14s,

matt neuthart is running a stock block and crank and is at 800 HP or so the block has thicker main webbing then the 302 or 281 as well as stronger rods, stock split port heads also put stock 302 and NPI heads to shame

other parts of the car, not sure on the t5 trannys, but the 4R70Ws with a jmod and slight stall would be fine, the 7.5 rear would be fine to as long as you dont run fords crappy tlok, if you run a true trac and TA rear girdle it will handel more then enough power

im not trying to argue, im just pointing out that people who have never turned a wrench on a 3.8 and know absolutley nothing about them need to know that just because it is a base engine, it is far from trash

Well I have made my point. I have had this retarded conversation before. You may be living in a dream world. Continue turning your wrench.

yes you can, is it worth it, absolutely not, the crown vics use the NPI heads, so you will gain 10 rwhp or so at the most

Not true all 2001 and up crown vic engines are PI same heads and intake as the stangs with the (PI) engines

all pre 01 engines are NPI and will gain almost nothing

but with the pi engine you will have basically a gt

but with the pi engine you will have basically low-mid 14 second V-8 when you could have a mid 13 second V-6:wink:

drop a 5.4L navigator engine.... borrow the intake manifold from a 99-01 cobra...... dyno tune and perfect the crap out of it, swap out all the usual stuff with an engine swap... tranny etc etc.

navigator = intech... intech + 5.4L = GT500/ford GT block with a breathing problem and a lack of a roots blower with a major detune


viola..... 2000 cobra R with V6 badges and a crappy suspension :grinyes:

The time and money you spend to switch it over, you could have just gone and bought an original GT.

As for the 3.8 being "far superior than the 4.6". Stock for stock, the 4.6 is better with hp/tq. If it wasn't, they wouldn't have GT's with 4.6's. They would have 3.8's!! However, I don't disagree that the 3.8 can be MODIFIED/BUILT to run with and over STOCK GT's. And yes, it can be done without spending a mint but, if you spend $2,500 on the 4.6 compared to doing the same on the 3.8, your hp/tq #'s are going to be alot better with the 4.6. Just like Stang2000gt said, I am not dogging the 3.8. I've seen some good #'s from them with basic bolt-ons to S/C, NOS, turbo's. If it was me though, I would rather have a GT with the 4.6. Just because you know the other parts around the engine are made to handle the abuse. With the 3.8 Ford knows that MOST of the owners are not going to be racing at every light.

SORRY FOR THE BOOK

Just because you know the other parts around the engine are made to handle the abuse. With the 3.8 Ford knows that MOST of the owners are not going to be racing at every light. The Ford 3.8 is a stout little engine. People have been running 10's long-term with the stock bottem end, heads, cam, ect. for years as I'm sure you probaly know. I also know from experience, I've been running a 100 shot untuned(on my 87 perf tune) that doesen't shift out of first until almost 6k, I've sprayed it off the line countless times, I've sprayed it below 2.5k in 1st MANY times which is hell on the bottem end, I have my stock heads/intakes and still have the piston no.2 issue, and I have my 7.5. I've sprayed it like a whore for over a year and am at WOT normally a couple times a day, I beat the shit out of my car and the ONLY problem I've had is I had to replace my alternator at 50k. People assume that since it's at the bottem of totem pole that it's weak, and thats far from the case.
