@CudaRay, have you tried contacting a local Mopar car club in your area? One of their members may have something available.
Here's a link to one in the Wichita area I found on the web...
That's good idea! I did find a seemingly good block for $100. Balancer bolt broke causing the crankshaft to crack. Supposedly no ridges in the bores and no visible cracks. Only problem is its over 2hrs away.
