I joined this site in hopes of learning some tricks on swaping my 2.8l v6 outa my 86 s-10 blazer 4x4 auto for a 4BT. I want this to be my daily driver that gets 25mpg easy.... is this or is this not legal? I will be tagging it in NC and have seen that it is not allowed.... any info would be appreciated before I start getting parts together. Thanks -Justin
