I have seen several places that the 261 is a full flow motor and that the 235 isn't. What does this mean, and what difference does it make for a daily driver? | | |

This is why you can't plug the holes on a 261 oil filter.
54 3100 with 235
62 flatbed dump C60 with 261

Is a bypass-flow oil filtration system found on the 1954-1957 261 truck engines (as it was on the Canadian Pontiac 261 engines)? http://www.oldchevytrucks.com/cgi-bin/htmlos.cgi/0075.2.3940963852016169258 Tim | | |
