Down, but far from out, my 280z remains.
A lot has happened since early summer, but to sum it up quickly the machine shop took forever to work on the motor. So long, that I completely got out of habit of working on the car. Some other work was done while I was bored, as long as it didn't cost and measurable amount of money (the aero and tail lights were free). The engine came back from the machine shop cleanly bored and decked moths later, the entire rotating assembly balanced together.... and went straight to the back of the garage. And so it sat. I sold my beloved Harley Davidson to buy a reliable daily driven Mazda, and have only recently begun collecting the rest of the parts I need to rebuild the L28. Clevite bearings in standard size were remarkably hard to find from one of my usual suppliers, so they were eventually found on ebay.
And so now it begins, the rebuild.
And now I'm not so sure about the L28... some better deals may have come along...
