mod motor blocks in general are good for over 2k hp. aeromotives car runs low 6's on a probuction ford modular block as well as production ford 4 valve heads. and the heads dont matter its the block we are talking about. a cast iron modular block is good for over 2k.

What did they have to do to it? Is it truely production or does it have billet caps, girdles, and all the other tricks to make it hold together? I'm not saying its not possible but I'm sure the block is pretty far from being truely production just for reliabilty reasons. Edit: I just saw you said 4v heads.

Power for this Pro car starts with a Ford GT 5.4-liter supercar aluminum block that's been milled by VT Competition Engines (Lansing, Michigan) to accept a Darton Modular Integrated Deck. If you're not familiar with the Darton MID design, basically the cylinder walls of the block are milled out, leaving an open rectangular shape. The MID consists of interlocking metal cylinder sleeves that are precision fit into the block.
Once that was complete, the block was filled with Hardblock, a concrete type of mixture that solidifies once it is poured in. Duttweiler says this was done mainly to prevent blown head gaskets from spewing water out of the side of the heads, which could possibly get under the tires. It also makes the block a lot more stable and less prone to distortion. Once the Hardblock has filled the block, the water passages are then welded up in the heads, and the only thing that the head gaskets have to deal with is cylinder pressure, which is easily accomplished. Duttweiler says that the small bore size of the modular engine family helps them seal better. Flatout Gaskets of Mundelein, Illinois, supplied the copper gaskets and O-rings that seal the heads to the block.

Come on man. The cut out over half of it for the Darton MID and then they filled what was left with hardblock and then welded the passages shut. I'm willing to bet it had billet main caps and a few other things not discussed. About 30-50% of it is actually Fords production block. It may have started as a production block but what it is now is pretty far from what it started as and is about as far as you can get without buying an aftermarket block.

Nope..I have to agree with Stop.
But, it's personal preference. Owned both at the same time, sold off the cobra, kept the mach, and still dont' regret it. Most will disagree, but it's a personal preference thing.
Not only that, if you talk to people that have owned both, most will admit that they miss their mach or can understand why someone would want a mach over a cobra. It's the ones that only have a cobra, or dream of having one that typically couldnt' or don't understand.
Disclaimor: that last paragraph was not intended to be offensive, simply a summary of what I ahve come across the last few years.

But, honestly, what 90-100% production block could handle 2k hp? Sleeving at a minimum would be required.

That was the point I was trying to make. There aren't any that I know of 100% stock that will live at that power level. Can they be made to live? Sure, but then they aren't stock blocks anymore.

I remember back in the 80's seeing an article about a 302 turbo build. They put so much boost on it that the heads were lifting off the block. It made over 1200HP before that happened though. I think it was a Duttweiler project if I remember correctly.

On a side note, there was an old article that tested a 289 K-code motor with minor mods.....IDK how many of you know, but that motor will handle 8k RPMs, from the factory, no problem. (one of the reasons it was used in the shelby cobra and original GT40)....but...they put headers on it during the motor dyno test....after holding that rpm for XX minnutes, the headers were BRIGHT RED and started to deform.
I'll have to try and find it online.
