The 4.6L came with a aluminum block

Aluminum would be more prone to failing than cast iron when adding a lot of boost like turbos or S/C's. Also if you overheat it bad it could warp the block.

Thats why 03-04 terminators went back to iron

I remember somewhere they weren't sure why the Terminators went with a castiron when the aluminum block can take 1000HP. I know ford did it more for the insurance/just incase for the 03-04. Also i don't think it would be no more prone to warping than the aluminum heads that they have. The heads would warp before the block.

The "strong" aluminum cobra block (teksid) only came in the '99 and down cobras. Some 01's received the Teksid block but most received the much weaker WAP (Windsor Aluminum Plant) block. The teksid blocks were very strong, made in germany and had 6 bolt mains. The teksid block is a much better block than the iron block on the 03/04's, almost as strong and lighter. But as previous post say ford wanted to ensure the reliability of the terminator.

Check your car and see which is in your car.....

Where some of the aluminum blocks also made in Italy? I've heard that before I belive it was one of the companys that makes the farrai blocks,(this is what I've heard).

I think the Masarati had the 4.6 cobra motor for a time

Speaking of "masarati". I seen one yesterday on the highway!
Mother of god was that fast!!! And sounded dam good too~

Yeah they definitely have an exotic look and great interior.

They were Teksid blocks in the 94-99 and a few in the 01's. The Teksid blocks are rated for 1000hp or past and are lighter than the iron blocks by a fair margin. There really isn't a drawback to the Teksid block, its not like you are going to be able to street drive a 800+hp car.

The weaker Al block that Ford put in the 01's is still decently strong and light.

As said before. The Al heads would warp before the either of the Al blocks.

I would really only own a Teksid block Cobra. I like the fact that they are actually trying to be somewhat lightweight instead of the other Cobra's who just add power to offset the weight and expect the handling not to suffer.

So the 95 cobra had the "Teksid" alminum block or the iron?

94 and 95 cobras used a Cast iron windsor block....

I had heard that the Teksid block was strong but the internals were weak.
