MBHD,
On the Larrowe website, under "Misc. engine parts" they sell a 6 3/4 and 8 inch Powerforce damper. They are for SBC from Professional Products and and according to the PP website they weigh 9.3 and 12.2 pounds. Larrowe says they fit the 194 crank snout but "In all cases the crankshaft must be drilled and tapped to 7/16" and an SBC vibration dampener bolt kit must be used."
