Hi all,
I recently got a 519 engine to use for restoration of my 1957 Corvette race car and the engine code is CY, which is for the 283/275 aluminum head engine that was reportedly not released. The casting date is A50. The pad date is F404CY, probably for March. This engine was a dealer replacement for a 1960 283/290 and was put in in the early 1960s, probably within the warranty period. It was rebuilt in the past and and shows light machining swirls on the pad. The font and spacings do not match what is on other pads of the period, but then there's no apparent reason for someone to have ever tried to restamp the pad. So, I wanted to see what the experts out there thought.
Thanks,
Bob
