Cost me $90 to have the mains (and rods) ground and polished, $75 for zyglo/crack check, and cutting the counterweights was free because I did it myself with an angle grinder, using a cardboard template (cut 7.25" hole in cardboard, cut piece of cardboard in half). Grind to fit the template, polish it up with sandpaper rolls, and that's that. Not much material needs to be removed.



how much metal needs to be removed? .125" or less? i'm thinking about just doing the 400 with the stock stroke. what kind of abuse can a cast crank take? i know i wouldn't want to throw a 250 shot of nitrous on it, but what about just spinning it to 6,500- 7,000 rpm? will the cast crank take it? my buddy that's been in mopars all his life says a cast crank in a bb mopar wont last, him or his dad ether one won't run one in any 440 they us.
