I Feel overlap is the most over looked camshaft spec, lift is the easiest spec to figure out. I like David Vizards approach, figure the LSA and overlap you want/need and the duration will take care of itself.
Not saying got to follow his formula 100% just like the basic idea of it.
Intake closing for me, a person can do alot with a big cam or a small cam to deal with one accepted pump gas compression. Plus if your doing a stroker you want to use the cubes available & and not throw it away .
