It has a $15k list price. Aftermarket Ti rods at $500-800 per rod, are custom machined from billet. These are volume forgings, possibly over 10,000 sets per year; 80,000 rods. That is probably more Ti rods than all other sources combined.
The huge balancing pads in the pictures indicate a production quality level. I would be surprised at a price above $150-175 per rod, and shocked at a price over $250.

Useable titanium alloys run about $80-100/lb Figure pre-machined weight of 2lbs per rod and you're looking at close to $200 in raw materials. Factor in other costs and GM is spending ~$220-250 per rod. Now, what do you think there going to sell them for? cost?

That would be $15-20M of titanium per year, and about 8% of the manufacturing cost of a Z06 and 10-14% of the purchase price of a complete LS7. Does that sound realistic?
First, what is the source of your price information. I have not found bar prices on-line.
Second, if the prices are that high the volume manufacturing process would have less waste (45% in your estimate).
Third, just for LS7 production, GM will by 40 tons/year at 2lb/rod using your estimates. Probably sourced overseas. That should allow a negotiated price.
Fourth, titanium is showing up in various cars, especially for valves (Nissan). This also indicates volume prices for the grades being used for these parts can't be prohibitive.
