    Lq9 - 427?

    Anyone ever get one of those 6.0l LQ9's and bore it out (or stroke it) to a 427? Do you think the extra weight from the iron block over the aluminum would be compensated for with it at 427 instead of 408?

    It's 2:30am and I can't sleep a wink.

    lt1 cars have the iron block and they run good, yeah a little heavier in the front but with cast iron block it will hold more power longer, not saying that the aluminum wont handle, but just not as much

    me personally, i would go aluminum, i like the way it looks, its light and i dissapates heat better, your choice but think of it as what you want, 100 on the front of the car where launching becomes more of an issue, or do you want another 19 cubic inches, the 408 will create more than enough power

    I think the biggest I have seen is 421.

    The weight isn't nearly as big a deal as you would think. 80 pounds or so more is all.
