Well you'd think it wouldn't be hard to find that info, but I searched the web and couldn't find the advertised duration anywhere.
Rock Auto has all the other specs as noted above, but no advertised duration:

edit:
RA's site above showed Alternate/OEM Part Number(s): E908P
I looked up Elgin E-908-P and found this site with a pdf catalog. E-908-P on page 9 shows the advertised duration is 308º.

That seems a bit short for 233º @ .050" lift.
The site below shows the same E-908-P part number with 329º advertised duration, which matches the factory Olds specs for the W-30 manual trans camshaft:

Maybe manufacturers are getting away from posting "advertised" duration anymore because they know that duration @ 0.050 is much more useful information and nobody pays attention to the "advertised" number, anyway.
