I'm not concerned with the outward appearance; mainly just the engine and upgrading the performance to what the 4.6 offers. I have a 4.4L apart now and am thinking about boring it out, sleeving it to get it to 4.6L but what else would I need aside from new software? Would the transmission not be able to handle the extra power? Dinah sells a S/C kit that brings hp to 412, which is impressive.
