I think someone else already said this,...
Jack did an excellent analysis of weight savings. It's a lot harder than you would think.

I don't think you can pull quite 200 lbs out of an iron 351-C. I've spent a good portion of 30 years lightening up our street Pantera L. Although it looks stock on the exterior except for a Revson chin-spoiler, the car in fact now weighs around 2690 lbs ready to drive, and it still has the 351-C block in there along with stereo, heater & A/C. Only the heater is stock. In 1981 when I started this li'il hobby, the car weighed 3250 lbs during a tech session on Longacre scales.
So- a stock displacement 351-C weighs about 575 lbs fully assembled (guesses vary) and its possible to lower that to around 425 lbs. The Auto Industry reckons that removing weight from a design already in in production costs around $100/lb removed. The Aerospace industry estimates far more cost per lb. removed. They are both correct if you count labor/hr as well as parts changed or redesigned.
