Actually, I was thinking of Mount Hermon Rd. Kings Mountain is off of H35/Skyline Rd. Anyway, I lived in Los Gatos for awhile and use to go to a Wed night cruise-in at a shopping center on Mount Hermon. Don't know if they still do it or not. Also, after I lived in LG, there was an auto shop/biz sponsoring a get together at their place in Scott's Valley.
Re: the parts interchangeability. As mentioned above many (if not all) will bolt on but some may not be optimal for a 408. Ex: The Performer will bolt-on and work but I'm sure it's the 318/360 version with the smaller ports. Again, will work for now. Although not mentioned, I'm guessing the carb is a 600-625 cfm (vac sec?). Also will work but might be on the smaller side. A lot has to do with the final cam selection and head/mod you select. Everything else you mentioned will be fine (you may want to inspect your water pump before installing). The driveshaft also sounds like the right one now that it is clear it is out of another A-body with a 833/8.75 setup. One last thing: Inspect your trans components (ex: pressure plate, flywheel, etc.) before installing as well. Sounds like you are on your way.
