    General information, please...

    What is the difference in weight between a stock Buick 455 iron block and main caps versus a "Standard" configuration TA 4550 aluminum block with main caps?

    I understand that the aluminum block (and main caps, I assume) is a much beefier product than the stock block (the primary reason for it's existence), but I'm interested in the weight difference too.

    Thank you.

    Well, I know the TA block with caps weighs 176 lbs.

    I'm going to guess that the iron block with caps weighs about 200 lbs or so.

    OK, so the real benefit of the TA block is greatly improved strength, oil distribution, displacement limits, etc. All this requires a lot of aluminum (i.e., mass).

    Sounds good to me.

    Thanks for you imput,Larry.
