Very nice ryan. I think you should use that 331 kit, and for the love of god leave the interior alone, it is too nice, just do some aftermarket gauges.
im thinking of doing just black carpet. thats it. but some panels are faded so im not sure what to do to like bring them back to life. i like the grey. but black on black on black would be so sexy.

.. i'll throw some cash your way for it!
3.73's would make it a little more fun lol. just need to get speedo gear. diff fluid. and some under coating to do the rear end up in before it goes under there.
