NICE!  That mid-range torque should get your 56 down the track very swiftly.

Moon Shadow,
running 37/34 tooth combination (1/2 " pitch) to overdrive the blower, achieved 10.5 # at 6100 rpm. had topped out boost @ 8.9 # with 750 carb, boost (and power) jumped when 950 carb was installed. Blower is old school rebuilt for street use with no modern teflon coated internals.  Power was still climbing @ 6100 but so was my blood pressure, stopped after reaching 500 hp target. thanks for your interest !  Dean
