Not a engineer or metallurgist. Get into a discussion on forged vs billet components, with them. 4340 forged is the strongest way to approach a high stressed part like a crankshaft. Crower is one of a few that has a forging die for 8 counter weigh mopar crank.. You have to have a die to forge a crank.. They all start as a billet piece of steel. You can make any thing billet that's why they are popular. Upper level billet cranks are made from EN30B material. A higher level of material strength because i needs to be to tolerate its lack of twisting strength. 1500hp.Good 4340 crank, no worries. My 2 cents.
