the Cobra is a niche car..

Koneiseggs v8's make and made more power

oh and if such low numbers makes it not a production car then how is the Veyron the fastest PRODUCTION car in the world?

seems like the industry itself thinks you are wrong.

THE cobra may be, but the shelby is not.

True, we've seen what some of the iron block 2003/2004 Cobras and GT500 engines were capable of handling and of course the awesome Ford GT with it's aluminum block as well.
I'm just curious if these later (2011-2013) aluminum blocked Mustang GT500s have quite as high of a power limit as the previous iron block counterparts had.

according to one shop the block is good for 1500hp.

How exactly do you figure that a car that comes off the same Ford production line as every other Mustang, is a niche car? Those Koneiseggs can't even be registered in the U.S., while the Shelby can be sold and driven in just about any country in the world! Hell, my car puts out almost as much power as a new 2013 GT500, but the engine had to have a lot of work put into it over what the "production version" came from the factory with.

i hand't known a number on the new 5.8's, but i had seen plenty stating that the old 4.6's were good to around 700 on the stock blocks. i don't have any personal experience with that though.........

I wonder how many people need a block that can handle 1000-1500+ hp in a street car? Seems to be more of a bragging point than anything to me. Kind of like factory posted Nurburgring lap times. I'll take the lighter aluminum block any day in a street car. For those that want to build a crazy Texas Mile, drag car, etc. there is the aftermarket.

I agree, I too would MUCH rather have the lighter aluminum block (be it a 4.6L, 5.4L or 5.8L), especially considering that it might even take almost as much boost as the older/heavier iron ones anyway.
I would think that the actual internals themselves probably mean much more than the block material anyway.

i'm sure they are guessing at that number for now until they can push the limits to see for sure. like it was stated before the internals are probably more important because you can always do things to help strengthen a block to help get it past it limits.

the blocks on these things seem like they are pretty stout. i don't think they need to change much on them.

Several guys in the 5.4 for the 11-12 GT500 have made over 1000whp on stocvk blocks. SO this one should be in line as well.

Good try but...forget it,who Im a kidding, it was a lame ridiculous try.

So then why does GM have to pay back thier loan if it was given to them? Wouldn't that fall under the same terms as ford? Plus if it wasn't for the government giving the big three money they already proved that ford would have filed bankruptcy within months so they just had better timing that's all.

GM received BILLIONS in taxpayer money, then filed bankruptcy. Then, after reforming as New GM, they got a loan which they repaid. That loan was a fraction of what they received and didn't pay a dime back.

Ford got a loan and paid it back. No free hand-outs with no repayment.

Big difference.

^^ Thanks guys, but the horse is dead and rotted. Let's keep this thread on topic.

Thought Id stir it up a little bit for some friendly conversation

1ltcap

if the 5.4 were capable of that, and we know the 5.8 block is improved over that, then i'd have to think that the thing could support some insane power levels.....

1ltcap

you mean the big 2.

Redfire 03

You're got to be surprised at the number of '13+ GT500's producing north of 1000hp. Won't be hard at all with a KB or Whipplecharger.

Didn't the additional 0.4L displacement come from increasing the bore only? I know they used a new cylinder liner technology to achieve this, but increasing the cylinder bore (while keeping the same bore spacing) is the LAST thing you want to do when it comes to block integrity.
