Here is a link to a cam lobe picture that I found in a members car in 2014. At the time Jim Brierly commented in the second post that it did look like too small a followed foot for the lobe grind. Any more opinions?
Not a Model A or B grind though but an English Ford 10 regrind.
I once installed a radical high lift grind in an English Jowett Jupiter with a small follower foot. The edge caught and chattered the cam lobe very quickly. I mushroom-ground the followers and alleviated the problem temporarily, but then got rid of that cam and went to a different set up.

Oops, I cannot seem to make this a clickable link. It works if you "open" it. I used the paperclip icon to post.
Advice please.
