A duration at .05 of 245 or 250 with a lift of .650 is slightly warmer than mild, the idle should be reasonably pleasant. As I recall, the original sideoiler cam had a similar duration, albeit with less lift and more overlap. When it comes to cams though, I tend to go with one that has been used sucessfully in a similiarly built engine -- was this specific cam recommended to you? You should be aware that there was an ongoing debate on whether solid rollers have an adequate life span in an FE. At one time, the recommendation was that a solid roller cam in an FE needed to be pulled out and replaced periodically. That may have changed though in the last few years. Perhaps one of the more savvy FE builders can give an update on that.
