I'd love a 4" strock SBM USA forged/USA machined crank in the same price range as their USA forged/USA machined SBC cranks, maybe a cast crank option in the $400 range if it was cast/machined in the USA.

I'd really, really love them to make their powderforged rods in SBM size, or at least 6.125" SBC, with the little end designed such that they could have a SBM pin size option without having to do a lot of spendy rework. those powderforged rods look like they'd be awesome for a street build up, or any application where you're looking at under 600HP or so.
