Teksid Block Question

I have found alot of threads on this, but they are all different. I am wondering what years the teksids were used in what vehicles. I know the 96-98 Cobras had them and thought that 92-98 Mark VIIIs did too. Some say only the later Marks had them. And were part of the 99 Cobras Teksids? If anyone could help it would be great.
 
Unless you already have aftermarket internals already, your block will not be the weak link. The "hyper-crap" rods/pistons in the factory 01 engine will be the weakest link (~450hp seems to be the ballpark limit before breakage rears its ugly head).

Run a search for prior engine failures to learn more.
 
Just curious....but why the fascination with a Teksid block? I know they're tough and all, but nearly all of the production modular blocks iron or aluminum will handle 600-650+ hp with little fuss (save for the pre-'95 iron ones found in Crown Vics, Marquis, Lincoln's, T-Birds and Cougars).

Unless you plan on pushing the envelope way past that, I'd think you were going overkill for no reason?
