I,m thinking about doing the 393 stroker in the future. I know that a forged crank is stronger, but At what point is a cast crank no longer a good choice. Is there a hp that is to much for a cast crank? Also what about the rods, at what point do i need to upgrade?

right now, the "magic" hp limited number for a cast crank is somewhere between the mid 500 to 600 hp level, HOWEVER, this doesn't include "power adders" (nitrous, supercharger, etc). If you plan on something that gives the engine that extra "jolt" you may want to step right up with a premium 4340 forging.....
