I am not going to let this one slide. I had a factory 440 forged crank turned down to 400 main size and took .125" in radius off the counter weights. I used a 6.76 H-beam 440 length rod and a Ross forged piston. Wound it to 7,200 rpm where it was making 787 HP on 91 octane pump gas. It is now de-tuned to 580 HP and running in the shop truck. No, I think the factory 440 forged crank will hold up just fine.
