New to the forum but not new to fords. My question is I have a donor 1994 4.9 in a wrecked truck. Been looking for a shell to transplant the engine with no luck what-so-ever. I have found a 1996 5.0 with a blown engine. I know the trannys will bolt up. Will the transfer work. So what would be involved in transplant. Thanks in advance for replies.

the 96 is going to be obdII so your computer and wiring will not work from the donor, for starters.

 

Thanks for your reply thats what I wanted to know if the computers would work or not. Thanks again, my search will continue.

You have to swap the engine harness and computer. You would have to do this anyways to switch from a 5.0 to a 4.9.

 

but the obd I stuff isn't going to work in and obd II (96) vehicle, right sean? i doubt you'd be able to pass any kinda of inspection, etc

 

yeah its illegal to swap in an engine thats older than the car your putting it in

 

Yes, that's right. It won't pass inspection because you can't legally make an OBDII truck OBDI, but if you didn't have to worry about inspections you could still do the swap. You can use an older engine and still pass inspection, as long as the engine management system stays the same.

 

I've never heard of this before. Learn something new everyday. What will they do fine me for putting a different engine in MY truck. Sounds like BS to me.

 

the engine doesn't matter you just have to have an obdII computer and wiring on an obdII vehicle.

 

Technically, the way the law is worded you can't use an engine older than the vehicle you put it in. But in reality, since the engines are identical other than the bolt on computer controlled devices you can use it and it will run the same as it was intended for that year. It's the same reason you can't use a carburetor on a fuel injected vehicle, because you have downgraded its emissions technology.
