Juice!! I've seen the damper for a small block chevy used. The crank snout is the same diameter. The ATI is available with a poly-groove pulley built into the outer shell as well as other options. They offer mandrels to run toothed, (blower drive) pulleys as well.
Panic, I'd like to see that video of Isky's harmonic demonstration!! I remember Smokey Yunick's demo with the electrically driven engine assembly, (basically a V8 compressor) and some of the research he developed.
