Does anyone know how I can identify a 2.4 crank for my stroker setup. I know I'll need a 6bolt crank out of a g64b or g4cs motor. I just want to know if there is anyway i can ID one of these cranks just so I can make sure I'm not getting hosed and they're actually giving another 4g63 crank or just anything like that. Is there a part number, ingraving, measurement i can look for? Thank you.
