I see some guys mentioning low end power being better with the cam the op chose, a 4" crank will have tons of it with a much bigger cam. When I spoke to Dave Hughes about my 408 being fastest shifting at 6400 he told me I didn't have enough head flow and that cam should like 7200 or so. He also told me the cam was to big for what I was doing. I'll agree with him on it running out of air but not on it being to big. It had power everywhere, down low, mid range, it didn't matter.
From my expierence if you build a 4" stroke engine and it doesn't have a butt load of low end, you have made a serious mistake somewhere. Either in choosing parts or on assembly.
