I talked to someone in the business about the flathead Ford rod today, and he said they'd custom machine their H-beam rod to 2.1 Chev rod bearing, but said their forging would be best @ .787 pin. That would give a 7" rod, but would still require custom pistons rather than off the shelf. They would need to have 10 orders to reset the machines and not have to jack the price real bad. They'd still approach $100 each however.
7" H-beam, 2.1" big end, .787 small end.
