Answer
The block is a 1948 design, introduced in 1948 and used in 1948 and 1949 and 1950... the casting date code is March 29th 1949, and the engine nunber indicates a Chevrolet truck unit, 216 cu in, oh and a 1949 Model! A light commercial, 1/2 ton to 3/4 ton would have a 'C' prefix, and 'X' indicates a 1-ton and above unit. Hope that helps!
Blocks were at the time cast by McKinnon Industries Ltd of St Catherines, Ontario, GM of Canada subsidiary since 1929 and they used 'M' to indicate their manufacture. However the engines were assembled in Windsor, Ontario Transmission Plant until 1962.
