Your problem with the camshafts could be caused by a lack of zinc in the oil you're using, or it could be too much valve spring pressure.
Some of us -- surely Tom the Beater and i -- would rather have your wild, blown 270 than the 4200, but we're from the past, as i am frequently reminded. Still we shall certainly be interested in what you achieve with the 4200. It is the future of inline hotrodding, or part of it.
God's Peace to you.
