It’s the first year for the successful Chevrolet V-8. (This basic small block design continues even today over 50 years later.) One very unique characteristic of this first year V-8 is the lack of a traditional block connection for a positive flow oil filter. For this one year, this 265 engine carried the by-pass oil filter system much like the standard 235 six cylinder. It was dealer installed!
The filter canister has a welded on right angle bracket that is secured under the thermostat housing at the front of the engine. The supply and drain lines are small like the 235. If the filter becomes clogged and the oil stops flowing into the cartridge, the engine continues to run with good lubrication. These photos show an excellent example of the 265 V-8 accessory oil filter system, with it being a dealer accessory, it probably was placed on few engines when they arrived at the dealership.
