After dozens and dozens of email and phone inquiries, plus countless searches on Ebay and the CORSA website, it appears I have a line on my rebuildable Corvair engine. It is a 110hp 164cid engine with an RH engine code (that's a good thing). It is currently in a car that is destined to be parted out by California Corvairs in Corona. Once it is out of the car next week, I'll look it over and buy it if everything looks good. (Time: 0.5 hours)
