You're right GMCPanel. The "balancer" on the 151 is just a short flange hub like the original 265 and 283's had. There is no split-ring balancer like we're accustomed to seeing. That doesn't mean that it won't work, though. All those old V8's ran fine without a dampener, and lots of them didn't even have a crank/hub retaining bolt. They were merely pressed on like some of our sixes.
The only issue still there is how to connect the blower brive belt, since the 151 serpentine pulley bolts right to the hub and sticks out about 3" to line up with all the rest of the pulleys. I would bet that the Pioneer catalog referred to above might have a solution available for that, too
