Pontiacman,
I hear what you are saying, I've been on ebay for 12 years, and have a 100% feedback rating, buying and selling, but still, there is no feedback about the blocks, most of the feedback is on the injectors.
I haven't made up my mind as to what I'll be doing with my truck yet. It's started to use antifreeze, but it's not showing up in the oil, or externally, so it's likely a cracked head, or a head gasket. So far it's not causing any running problems, except having to add antifreeze.
I figure that I have some time to decide what direction I want to go, and this guy's blocks caught my eye, so I was trying to find out as much about him as I could.
