Let's make this perfectly clear. As much as Mustang fans (this author included) would like it to be otherwise, the 2010 Shelby GT500 does not use an aluminum block. At least a couple of times over the past few weeks, there have been online reports that the cast iron block of the last generation has been ditched in favor of the lighter material. These reports are incorrect.

At the Ford preview briefing just before Christmas, we explicitly asked SVT chief engineer Jamal Hameedi if the block had changed, and he told us that it remains iron. When the aluminum rumor popped up yet again yesterday, we contacted Ford spokesman Alan Hall, who repeated the iron refrain. Whatever Ford's reasoning was for keeping the hood closed on the GT500s at the Detroit Auto Show, it is not because they were hiding an aluminum block. The reason for the iron block is that the aluminum unit from the Ford GT is designed for a dry sump lubrication system and there is nowhere to package the oil reservoir in the production Mustang.

      the engine is exactly the same EXCEPT for the intake tube/filter and tube. there are pictures of the engine on the web.

      i could should you a handful of places where to place that oil reservoir in a stock mustang . lame excuse =(
        • 6 Years Ago
        The real excuse is COST!
      • 6 Years Ago
      I think there is some over the top reactions to this.
      The Cast block will weigh what? 500lbs?
      If is was made of aluminum, it would be, lets be generous, 250lbs.
      So, yes it would save you 250 pounds.
      ...That's one big extra passenger, worst case.

      ...Unless you plan on attending every track day you can. I don't really see this being a big deal.
        • 6 Years Ago
        Its a big deal with weight distribution. 250lb is a LOT when any or all of it is directly over or IN FRONT of the front axles.
        • 6 Years Ago
        250LBS off the front of a car is a huge deal when it comes to handling, although I don't think the difference is that much. Probably closer to 100lbs or so.

      They could stick that oil reservoir in the passenger footwell just fine.
      • 6 Years Ago
      I'm surprised it doesn't have drum brakes...

      It doesn't, right?

      But still, at least they got rid of that damned fender mounted antenna.

      Hey i heard the 2011 mustang is suppost to run on steam ? you also have to use a crank to get it started? anyone else hear the same rumors ?
        • 6 Years Ago
        Yeah, I heard that too. The same day I heard the new Prius would run on pixie dust and then heard about a Toyota muscle car. Oh! Wait.
        Toyota= muscle car. Nah. That's an oxymoron.
        But then I did hear one that is believable. Every new owner of a Tundra will be provided with a tow truck escort for as long as the warranty lasts.

      You can always drill it full of holes and plug them with nice lightweight JB-Weld :)
      • 6 Years Ago
      So it basically could have been faster if they had used Aluminum.

      My question is, when will nanotechnology give us an ultralighteight - ultra strong Engine?

      No doubt it will be in some 2 million dollar race car like the Veyron.

      I would have expected nothing better from Ford, a company that lives in its past and will soon disappear looking backwards. Its only claim to 21st century presence is its european operation. put Detroit out of its misery, please.
      • 6 Years Ago
      Ford is behind the times, just as usual. Maybe by 2020 they'll finally use independent rear suspension. Oh wait, I forgot about lame excuses of how live axle is better for drag races, or how aluminum blocks spontaneously explode when given more than 200 horsepower.

      Before stupid anti-American people attack that decision, most VW engines sold today are iron block.
        • 6 Years Ago
        I'm in the US and I have an open deck aluminum VW block. :) Of course it didn't come in anything in North America and was imported, but its 32lb comapred to 96lb of the closed deck iron blocks.
        • 6 Years Ago
        There is nothing "Anti-American" about wishing for a lighter engine!!!
        • 6 Years Ago
        Nothing anti-American about not liking domestic cars, either.

        But I did almost spit a mouthful of coffee on my computer monitor at the McMentality of questioning somebody's patriotism because they may not like Mustangs/Fords.

        When I read stuff like that I'm reminded of why I don't admit to being American when I'm in another country...

        Aluminum is for communists!!
        • 6 Years Ago
        Thats right! Aluminum block engines hate our freedom!
      • 6 Years Ago
      I don't think anyone should be surprised. It's supposed to be the KR's engine, which was iron block. It's more durable and cheaper to make then. The bad end would obviously be weight, which is a huge factor as to why it will weigh over 4000 lbs like the much larger Challenger SRT8.
