Alright, I got acouple questions after spending a few hours reading/searching the forums.

I'll be swappming my 2.5 Duratech out of my 95 Contour SE.
And I'll be putting a 3.0 Duratech out of a '99 Tarus in it.

I've read a lot of posts of people running the 2.5 heads on the 3.0.
My 1st question is
1) Can I drop the whole 3.0L in and use the heads thats on it?

Also, I've read some posts about the transaxle/diff.

2) Can I use the 4speed automatic transmission thats in the Contour right now, will it bolt up to the 3.0L?

3)Also I've read about notching the block w/ pre '01 3.0 Duratechs, why is the block notched?

4) I've noticed that some people swap the heads so they do not have to reroute the fuel rail, ect this is not a problem for me. But I noticed that they're talking about some type of control module that you cant run w/ the 3.0L heads, is this true, and if so what module, and how do I go about disc onnecting it.

Basically I wanna do a full 3.0L 1999 Duratech swap.

What am I looking at getting into? And what are going to be some of the major problems am I going to encounter?

Also will the will the 3.0L bolt right up to the motor mounts?

Any information is helpful.
I've been working on vehicles as a mechanic for over 30years and I'm also known around the tri-county area where I'm from for building performance transmissions for over 35years.
When it comes to mechanics, I know what I'm getting into.
These questions are just prior to the swap, making sure everythings going to work, ect..

Thanks!
