Iron vs. Aluminum And Their Effects On Handling

[ADiCarlo]

So I thought about posting this in the swap forum, the suspension form and then I thought this might be the best spot.

From what I've read the difference between the Iron block and the Aluminum LS in weight is a total of 80 lbs.

Now with the amount of modifications we do to our cars such as moving the motor back, applying newer designed suspension systems including coil over suspension do you feel that this additional 80 lbs will make a huge difference on the driving characteristics of the car?

Furthermore, what have people done to really help achieve a 50/50 weight distribution in the car beyond moving the battery, to the trunk and moving the motor more center?
