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.
Im not sure about the Mk VIIIs, but all cobras 96-99 had the teksid block. On the 01's only the first half of the production year had them and the other half has the different block.
The following thread over on SVTP is pretty helpful for identification purposes: http://www.svtperformance.com/forums/showthread.php?t=192162 FWIW, block strength is pretty much a moot point/feature unless you plan on running gobs of horsepower...so don't dwell too much on it.
I plan on running a single 76mm or twin 67s. I just want the strongest block. My stock one i think will be the week link as of now.
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.
You currently have the strongest stock aluminum block put into a factory Mustang Cobra. However... is not the cast iron block in the 03's & 04's stronger than even the Teskid? U.M.
The alum blocks expand more at high temps, thus stretching the tolerances of supporting equipment. But do they crack?
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?
A GT47R 88mm is what im trying to prepare for. It will as you put it push the envelope. I know my WAP block wont hold it.
