Great post Bob. I have all 6 Corvette News issues from Oct/Nov 1974 (the issue that introduces the new '75s with a silver '75 coupe on the cover like mine) to Aug/Sept 1975. The June/July 1975 issue has a nice article celebrating Zora's retirement that year. Great nostaliga to look back upon.
I found an article in the Feb/mar 1975 issue on Fred Donsberger who was racing an 1965 coupe with an LS7 454 crate motor and THM400 that ran 10.85 @ 128mph at Cayuga in 1974. Ever heard of him? Supposed to have been the fastest street car in Ontario that year.
