    Smile How much does the LS3 weigh??

    I see that GM is making the LS3 motor a crate motor already. I am not sure what the LS series motors weight. So what does the LS3 motor weigh as a crate motor or the full dress motor for the Vette. I have not seen it listed. I have seen published that the SB Chevy with cast iron intake is 575 lbs. Thanks...

    Lighter then that...I want to say 450lbs somewhere in that range? Gen IV's are great motors.

    The LS7, with all of its weight-saving, exotic bits, is 454lbs. I'd definitely put the LS3 up near 500.
