Starter Torque rating

I went from a standard gear reduction to an OEM Denso RAM mini style and the 451 kicked over about 2X as fast as the old starter. The only direct drive starters I remember were pre 65 and a few year specific to a hemi and I think it was because the exhaust manifolds, or 4 speed. Try it, I know I'll never be in the market for another old style 35 lb gear reduction starter.
