1954 Corvette Owner Needs Some Help

[Rob]

One of our new members is trying to identify the engine he has in his 1954 Corvette. Based upon the information I have, it's not the original engine, but I wanted to see of any of the NCRS folks here might be able to help?

Appears to be a replacement engine. The 1954 block was casting #3835911 (located in a recess just below, and forward of, the fuel pump mounting boss, above the crankcase oil pan mounting lip). The "Z" code indicates a passenger car engine, although the block was cast on March 30, 1954; the correct suffix stamping for a '54 Corvette was "YG". The casting date is located at the right rear side of the block, next to the starter solenoid.

The cylinder head should be casting #3836241, which was used on all '54-'55 Corvettes; the tapped hole for the temperature sender did not require an adapter. Your casting date (B 2 9) indicates that head was cast on February 2, 1959 (or 1949): the casting date is located in the valve rocker area (under the valve cover) next to the #4 and #5 cylinder exhaust valves.
