Correct, Kenn- there are at least two completely diferent timing covers for 
the '70-'73 351-Cleveland plus another for the 351M/400-M's All use 
different timing pointers- that are at best only loosely indexed to the block 
anyway. It's quite possible to mix 'n match the pointers. Anyone actually wishing 
to know their true ignition timing should first find actual top dead center 
and go from there. 

Harmonic balencers also constantly slip and change the markings, so unless 
you've gone thru the exercise to find true TDC and made an index mark, just 
set the distribnutor to where the engine runs decently but doesn't 
death-rattle under hard acceleration, and go on to other problems. FWIW- J DeRyke
