The 351 Cleveland DOT 4 myth.


To often i read people claiming that the DOT 4 on the 351 cleveland heads means its open chamber heads.
Unfortunate thats a long living myth that is hard to kill.
The problem is that the myth is spread among many "fact" books and other sources.


Well here you have a video that kills that myth.
