Commando 273 cam specs

Miranthis said

I have been researching the posts on the Commando 273 cam specs as I rebuild my 66 Commando 273. My engine guy is asking for the "full specs" for the Commando 4 bbl cam including "duration at 0.050". From the stuff below, can I glean all that I need?

From 66fs 's post on another thread:

The Commando cam works very well. We measured an original 67 Commando cam with 50,000 miles on it at Racer Brown's Cam Doctor's Analysis.

Intake:
110.4* center ATDC
202.8* duration at .050 Crank degrees
.405" net valve lift

Exhaust:
110.4* center BTDC
202* duration at .050 Crank degrees
.414" net valve lift

From other net-sources, what the usual "published specs" show is:​

Are you going to have a cam ground or is your builder just wanting all the specs to get as close as he can to original? o one makes a replacement cam for those engines but you could always have one made. Oregon can grind you one if they have a core or regrind one you have if the core is in good enough shape. Krazycuda had the 340 cam duplicated by Delta cams in Washington State. That information to follow.
