B-Man - I will completely agree about the cost of building an ultra high performance 350 and a mildly modified 400 to get the same power. In my neck of the woods, 455's have been "son, haven't had one of those for years" for decades; while obviously the power potential is greater, not sure about the cost.

Much of my weight savings was because I NEEDED different parts, and the aluminum was not that much more:

Steel wheels were insufficient width for the tires I wanted
Desired wide ratio transmission
Using original RAIV intake with no crossover

I still have all inner fenders, insulation, seats, uphostery, etc.

When different parts are going to be used, why not lighter parts.

The problem I now have is the low first gear, the reduced weight, and the power is too much for the tires; I guess I went overboard

Jason - I looked unsuccessfully for years for someone with an English wheel to do hood and deck lid; is fiber even an option for a 1974 GTO?
