I was concerned with ramp speed with the XE cam, will be a little faster with 1.6 rockers.
Most people suggest to me around 240 @ .050 for a 408/416; I am being a little conservative because this is a daily driver street car that will sometimes see the track, not a "streetable" race car, but it is on the mellow side for a stroker from what I have read so far. I would say if a similar cam is streetable to you in a 340 you could definately go hotter in your stroker.
