Hi,
Does anyone know the cam profile for the cam that came in a 1970 YH 455 engine? There is no letter or number code on the nose of the camshaft.
I would like to compare the profile to a Summit 2800 and 2801.
Thanks,
Mike

Stock should have been the 067 (P) cam.
It's very mild.
273º-289º duration; centerline-112º; lift .407"

John,
Thanks for the info.
I could try to use a degeee wheel and dial indicator to find the specs, but I would rather ask the guys that know and work with this year group.
