Fat chance of that happening in this lifetime me thinks

I agree with you GMCTD on the nicks, bumps and bulges on that spacer under the block. There is definately something serious going on there.
That little jewel did not come cheap and is certainly there for a good reason.

Those angled areas very well may house a clearance slot for the rod nuts to swing through. Sure would like to see inside one.
Get real I want it in my truck running!!!!
