Wait to hear from someone with better documentation.
However, the block code looks like one from an October or newer 1953 Corvette 235 and was also used on 235s used in Corvettes and Powerglide equipped cars into 1955.
My information on the head code must be wrong: 1953 235
Here are locations of other codes. The date casting codes and engine serial number will give a better idea of year in which it was installed (and the applications).
