THAT is a forged crank! The cam could possibly be a 440 hp but I would get a bigger cam if you can afford it.With the crank turned 0.10 and no markings on the id pad leads me to believe thet the engine has been apart so I would check out the bore size and condition.You just might be able to re ring it and save some dough.My first 440 a body was a 71 duster.It had a re rung 440 with ported 516 heads and a 528 Mopar solid lifter cam.It was a 4speed with a 3.91 8 3/4 suregrip.On it's first trip to the drag strip it went 11.91@115 and that's on a 9x28 drag tire! Oh yeah it killed the 3.91 gear first round and shortly after it got a Dana 60!
