The 1953-1955 Corvette 235 information in my hp table was not completely correct. The 1953 through mid-1954 Corvette 235s produced 150hp. In mid-1954, the Corvette 235 increased to 155hp as a result of using a "high lift" 261 camshaft.

I have corrected the information in the stovebolt horsepower table.

Here's one reference about Corvette 235s.
