Can't help you as to a machine shop since my scarce Nevada connections are in Reno, but if you're looking to make hot-rod modifications I think Doug Dutra is still the man when it comes to all things leaning. He's not in NV, but he's the tech guru at slantsix.org. One of the guys at diyautotune.com has an MPFI setup on a Slant, which may be of some interest to you as well.
