I have a Howards M-4 cam for a 331 -365 Caddy . I lost the specs. anyone have old Howards Cam literature from 50's era ?
If no one has the info you can send the cam to one of the 'big-guys' like Comp Cams or Crane Cams to run it through the CamDoctor. .
Call Howards Cams and ask for Ben Herheim - 920.233.5228 (wait till Monday as everyone is likely at the PRI Show).
Looked at cam again It's stamped Howards M-4 , could be made back in early 50's . Cam is not a steel billet .
