One other thing ALL 460s had 4bbl carbs on them, and I have seen guys try, and put a 2bbl on them and reduce the fuel economy so that is nothing to worry about.
As far as what I have been upto other than work it's been pretty well posted on this site what I do in all my spare time. The wife just says it's my midlife crisis but that ok cause it's a lot better than some other options for a midlife crisis.
