Unless I'm mistaken there's next to nothing for the 194-230-250-292 series engines because of the fact there's no aftermarket crankshaft support. I guess technically the likes of sticking a 250 crank in a 194 is stroking (resulting in a 250). You can even get a 292 crank into a 250 block but it's tough to justify the work. I can't speak for the other inlines though.

P.S. I was just thinking if I could get a 250 forged aftermarket crank I'd like it to have SBC width connecting rods. Then I wondered if it makes much of a difference that the inline rods are wider? Stronger, but heavy I suppose. I would wonder if the greater compadibility of rods on the market would make it worth it though. Thinkin out loud.
