Guest Rob J Posted March 9, 2011 Share Posted March 9, 2011 Why would there be a 401 stamped on an LX 425 block? What do you guys think? Link to comment Share on other sites More sharing options...
RivNut Posted March 9, 2011 Share Posted March 9, 2011 Those three digits are probably some kind of date code or something else. The only thing you need to concern yourself with is the LX. The 401 is just a coincidence. Link to comment Share on other sites More sharing options...
1965rivgs Posted March 9, 2011 Share Posted March 9, 2011 401 is the engine plant shift number. These numbers progress as the year progresses and are loosely tied to the production date of the car. But in your case, since the engine is NOM, it doesn`t matter. The stamping could be any 425. Tom Mooney Link to comment Share on other sites More sharing options...
