Us it on the intake side. Then pick a exhaust lobe that suits the exhaust-to-intake ratio on the specific cylinder heads in use and/or the cars exhaust system in use, be it 4,6,8 additional degrees duration, or none..
Then it could be ground with any lobe separation desired. Now the question would be.... do they have on hand blank billet cam cores.

Steve,
When you go with more lift some numbers have to change. Comp Cams show the 3316 to be 157 @ .200". But they also have the 3196 which is shown as 288 236 162 .390

PS This is a graph of my simulation of each lobe and what the difference in lobe lift would look like. Mike / Pastry Chef maybe can post a better graph
