460 questions?

[mnm99]

I'm in the market for my first Cobra. I've owned Supercharged cars and Turbo cars. I like the looks of a BB in the cobra and the amount of power without doing that much to it. If I go with Aluminum heads, intake and water pump will there be much of a difference in weight compared to a small block with iron heads? I can get a Turn key 460 with the following for 7K. or a 351W for 6k. I'm still deciding on if I could find a build that someone started or one complete. Most likely I won't find one that is mine without altering it some. I have 40K to spend so I hope I can find something.

Thanks
