Upon finding a couple of cylinders really low in compression recently like 90 PSI, I dug the spare short motor out of the corner of the shed as it was buried in other Zed stuff. I have begun stripping it down for it has a date with the machine shop for prep work to house its new internals. The bore and crank are surprisingly in excellent condition so I am hopeful the rebuilder will confirm once he throws a mic over them. The pan had never been removed confirming no previous tampering had been done. I just hope the engine in situ lasts a while longer until it is ready for transplant. Yesterday it has started to sound like a very worked V8!
