Since this thread is coming back up does anyone have any en-lightening new ideas?

I have been a minor player in this thread but as for me, I have not touched my Duster going on 2 1/2 years. Lots of life stuff happened since I last messed with it. It's in storage waiting until a few things fall into place which hopefully will be sooner than later. Currently its an iron headed 416" with a 904 but have been contemplating putting an aluminum headed low deck in it. Need to get it running first so maybe the big block swap will happen sometime down the road.

In the meantime I have been working on my '68 Coronet which is being built as a street cruiser. Nothing lightweight about it and probably adding more weight than removing. No plans to break any land speed records or set low ETs with it so is what it is.

Let's keep the thread alive, these lightening techniques and ideas can help anyone looking for more performance.
