Need correct crank pulley!!!! Any ideas?

I thought it was my eyes, but with the later pix, that is not right at all...for street use. It looks like someone scabbed in some sort of idler pulley onto this engine. The tiny diameter at the strip is just to make the pump and alternator turn much more slowly and not pull as much HP from the engine.

The normal crank pulleys are dished and bolt to the face of the damper with 6 bolts. The center bolt does not hold the crank pulley on in the stock setup.

So you will need a proper length/diameter/thread damper bolt; that needs to be torqued to 135 ft lbs to make the damper do its job. That bolt has a very thick steel washer under the head to clamp that high load properly. Then that larger crank pulley and the 6 bolts to fit the holes in the damper.

You don't need double belts at all for standard use without PS and A/C.
