Classical Trucks

The earlier truck models as early as 1930 featured simpler engines and a higher standard durability. Popular models like the 1953 Ford F-100 introduced overhead valve engines.

From 1939 and up, the GMC six-cylinder was a high-pressure insert bearing engine — initially 228 and 248 cubic inches. Oil pressure readings should be 60 psi or 80 psi for GMC and 30 psi for Chevrolet.

Almost all Canadian-built GMC pickups prior to 1953 used the Chevrolet 216 engine, not the 228 and 248 type placed in U.S. GMC trucks. The Canadian Chevrolet using the larger GMC 228 and 248 was called the “Maple Leaf”!
