It is interesting looking at the numbers from the Summit 2802 verses a Pontiac 744. It hard to compare Adv. duration and overlap because of how Pontiac measured these numbers. But here are 0.050 and 0.200 duration numbers for the 744 that I got from Rocky Rotella and numbers I got from someone who actually measured a Summit 2802.
744 duration at .050" is 224/236 degrees.
744 duration at .200" is 128.5/140.5 degrees.
744 lobe lift is .2716/.2716".

2802 duration at .050" is 225/235
2802 duration at .200" is 131.5/143
2802 lobe lift is .310/.330
