engine swap from 4.6 3V to 5.0 coyote?
1 Attachment(s)
I have a 2005 GT Mustang. It just so happens I can get my paws on a 2011 5.0 Mustang GT engine, 6 speed manual trany, ecu, wires, and gage cluster. Car was t-boned but still fires right up no issues. My question lies in regards to for 8 thousand dollars is it worth it or is it worth more to build up my 4.6.......My 4.6 only had 49 thousand miles on it right now and its bone dry stock......please all input needed, let's make this thred the drool!!

What are your plans for the car? Do you plan to hold onto it for a few more years? Track or daily drive?
$8k is a lot of $$$ when you could use that $8k as part of a trade up to a 5.0 |
I would trade the car and put $8,000 down on a 5.0.
|
It would be unique, but I'd rather either S/C it before doing a motor/tranny/etc swap for less HP.
or Use that money for a trade up on top of the car. The newer cars are so much more than our gen, and I LOVE my car...but I'd get a newer 5L in a heartbeat. |
Listen to these guys. Trade or sell your 05 and get an 11-14 5.0. You will be money ahead and it will be worth something if you want to get rid of it in the future.
|
I just don't feel the body lines of the newer ones, those just seem to soft for me. I'm keeping my 05 gt for sure. But I've been reading up in the dohc 4.6l 3v, as well as the good old revamped 5.0. Both are awesome in their own leagues. But rather then go through the headache of swapping etc, I'm just going to start off slow and work my way into Mustanghood. Start off with the basic, learn my engine inside and out, and then go from there, thanks guys!!
I wouldn't mind the 6 speed manual though for sure... |
I kinda have the same question has you do friend. For now im more in the way to charge my 4.6 and then in the future maybe.. just maybe i could go to a 5.4 from the GT500 but not for now and i want too keep my 06 for life. With your 4.6 with a supercharger, pulleys and a few more tricks you can go 600 horsepowers, thats more than enough. Like i said before im with you, the 05-09 lines for me are much better than the new ones.. more bad *** imo :D

I have a 4.6L 3v in mine and my street tune for pump gas is 600rwhp @15 lbs of boost. You don't have to go bigger for more power. If you really want a big engine then do the GT500 swap and go 5.4 4V. You can use all the GT500 parts, headers, computer and such, so it's much cheaper. There have been several guys go this route.

It's a SOHC, not DOHC, valvetrain configuration. This, to me, is a positive of this engine in terms of smaller size up top. Some people find it a negative because it limits how far up you can rev or make power, but forced induction will overcome that! ^^^...obviously point proven I'm still learning...lol!! |

Totally understandable. I'm still learning, I think maybe mine is sohc as well. I have a 4.6L 3V. 2005 GT
^^^...obviously point proven I'm still learning...lol!! This is a cutaway drawing where you can see the single cam on the exposed part of the valvetrain. |

All of the 4.6L V8 engines from 2005-2010 were SOHC. If you look at the size of the cam covers and compare them to the cam covers of a 1999/2001/2003-04 Cobra or an '03-'04 Mach 1, you will see a difference in the width. That is one visible sign.

So true I just checked, compared mine with the neighbors daughters, yup the width is diff. So mine is sohc. Which means kick a$$ right?
I say, it's a nice streetable engine that runs on 87 octane with a solid torque curve. I like the one in my 2010 GT (last of the 3V 4.6s) because they took the improvements they made for the 2008/09 Bullitt engine and applied them to that model year. I think it really depends what you define as "kick a--" :) |

That makes since too after looking at the diagram my engine is more noisy on the left side, right under the cover is the cam? That must be a thin piece of aluminum I hope. Makes total sense now my Ford Five hundred sounded the same way, it was a sohc v6 sho motor, sounded like twins, why are ford motors kinda noisy? I'm a ford guy only owned to fords my whole life, and they both kicked you know what but under the hood you can hear movement. Kinda cool but push rods are super quiet why is that?
In the 5.0L, there were foam noise suppression pieces installed on the fuel rails in the area of the injectors to quiet some of the noise. Not really sure why the noise exists, and I haven't really compared it lately to an old 5.0L pushrod engine (or other engines in different cars). My hearing is kind of damped out anyway from too loud 80s music so I don't notice it - haha! |

Anyways the 4.6 3v is a fine motor, its only real flaw is a combuston chamber that is more prone to pinging than its 2v and 4v counter parts. Its a shame Ford didn't include the oiling circuit for the cam phasers in all of the mod blocks, how sweet would the 5.8 block from the current Shelby be as its all aluminum and features a bigger bore to boot. The taller deck height might have proven a little problematic under the stock hood but that extra 70+ cubic inches would have been worth it. |

Here's your 3V cam with the finger followers reaching the intake bank of valves as well as the exhaust bank of valves from just one cam (per bank): http://www.charliehorse.com/3V%20Camshaft.jpg And here's the view of the underside of the cylinder head. 2 intake valves, 1 big exhaust: http://www.charliehorse.com/3V%20Head%20em.jpg If Ford would have put the same level of engineering into breathing on the 3V head that they did on the new 5.0 4V head, I don't think there would be the 100hp difference. Because the 3V has less moving parts to push compared to the DOHC. The better breathing and the higher redline is a much bigger factor in the 5.0L/302's 420HP than the mere .4 liters/21 cubic inch increase over the 4.6L/281 IMO. |

Added to the fact there are 24 valves & roller followers working on the 4.6L SOHC 3V instead of the more typical 16 on a single cam OHC (8 in/8 ex) or Pushrod for that matter. A modern refinement of the all powerful 427 'SOHC Cammer', the monster of the 60's. Ahead of its time IMO.

I personally wouldn't drop 8k for the 5.0 motor unless it was built.
Those motors are high compression and I wouldn't feel comfortable doing any kind of blower addition to a 5.0. That's just me of course. I put the 5.4 in my car and am extremely happy with it. But that was after I pushed the limit of my 4.6 with a Saleen blower. I'd feel more comfortable modding the 4.6 than the 5.0 just because of the compression ratio. |

But in his situation he could drop the same amount of money (or near it) for a 5.4 setup with a blower already attached and make more power stock than he would if he bought the 5.0 then spent another 2k on a blower. |

If I had 5.0 to begin with then I might... but I don't know, after hearing about the #8 piston issues I'm not sure.
