A few questions on swapping

Alright. i may have a chance to get a 4.6 95 cat and i was wondering what has to be done in swapping the motor over to my 96 3.8 bird? from what i gather some wiring has to be changed but how much? is it a worth while swap?

You basically need to rewire the whole car, not to mention change the suspension, transmission and rear end to support the different engine. Could be worthwhile but very time-consuming. It all depends on what your goal is and what you're willing to invest (time/money-wise).

would need that much rewiring? could the harnesses be spliced together so to say? and stop myself from having to behind the dash and rip wires out? i know the suspension work and all is a cake walk but its the wiring that scares me

As I have it done it myself, I can't say for sure. But I know for sure pretty much all the wiring in the engine compartment has to go and the wiring that goes from the ECM to the junction connector in the engine compartment has to be changed. I don't know the specific about behind the dash or to the trans, but someone else who has the experience might be able to help more.

You know, for all the blood,sweet, and tears you are about to endure,,,,,,wouldn't it be easier to just find a cheap use long block of the same size and swap it out? I mean, the ECU needs the right O2 sensors(besides a dozen other sensors) plugged in to make this engine run right. You could always build up a powerfull smaller engine with a few mods and have a wieght savings over the 4.6(my Probe GT would do easy 1/4 runs under 11.5 sec with some lower end work/heads/twin turbos---all on 2.5 liters) . Im no expert, but as mentioned above, you would probably need a complete engine wiring harness swapped along with the computer.....but if you do this your way, let us know how it turns out--

I don't know if you have a ton of money / mods tied up in the 3.8 car but as cheap as you can pick these cars up now a days I personaly would just go out and buy a halfway decent 4.6 model and transfeer over any custom mods from the 3.8 to it. I only paid about $300 for mine and all I had to do was switch the trans out. I'd never worked on these cars before that and it took me like 3 weekends to do it and that was only because I ended up spending 3 of the 6 days screwing around drilling out the exhaust manifold studs. I only snaped one but they were so rusted that I just did all 4 and put a nut and bold setup in there instead so I'd never have to worrie about it again. I figure it this way if they rust up again who cares they are just nuts and bolts I can just cut them off and but new ones for like $5 and save myself the hassle. If I had to do the trans again I could probably do it in one weekend now that I know how it all comes apart and goes back together.

Yea I know how that goes. My t-bird sat for 6months before I got the cast to do the trans.

If you cant afford 300-400 i wouldn't recommend starting a project like this. You really have to have the cash to do it all at once so you dont have a car just sitting there half done. Besides 300-400 wont get you any further then a standard head cleanup on a 4.6l engine. The toleranceing is alot more prescie then the 5.0l of the 3.8l. In addition skip the carb job its 2006 and not 1976. The carb will be an easy swap but it has alot less potential and in the end it wont be worth it in terms of fuel econmy. Just something to think about though.

No offense but... what!?. Twin turbos come on thats not exaclty a standard mod plus heads, your still talking serious money there. A twin turbo kit has to be like 3-4K plus the head work and to get it tuned that is at least another 1K. So in the end your suggesting almost the same cost as a built 4.6l longblock. Plus the 4.6l dohc weights the same as my 2.3l ranger engine approximately 525lbs i believe.
