Had this right on the top of my head, yea sure I did, lol. I am sure I knew it at one time but not now and for whatever reason, I never wrote it down. Would anyone happen to know the correct size woodruff keys to use on a 56-62 235/261 cam and crank?
Dragsix Well I can't really bring it up either,have an ancient drawer full of those that goes back to my predecessors stash from the forties. Have a new cam out there just have to look. Hadn't even thought of woodruff in years,the kids wont know that one !!

Dragsix,
Here is a previous conversation on "woodruff" keys that I think has the basic answer to your question.
Also, this Common Item Page [gmpartswiki.com] provides the dimensions for the various common "woodruff" keys used for your application.
If you use the info from the above thread:

one possibility?: Width-3/16(.188) In., Length-47/64(.728) In., Height-19/64(.301) In
another possibility?: Length in Inches--3/4 Width in Inches--3/16
??
It appears the one you may be looking for is GM# 106751 (see screenshot below).
Many thanks! I ordered a pair and will wait to see if they fit or not. I really appreciate the help. My youngest son decided he wants to build an inline six for his 57. I have one last 261 block and nearly everything else to put it together, except for those pesky keys, lol.
