I did the crank for my 471 in 2002/2003, so the pricing is a bit dated. As already stated, the chinese forgings now make it tough to justify doing your own.

Cost me about $750 to have the counterweights turned, the mains reduced and the rods offset ground, plus a competion balance. Machinist took more off the counterweights than needed, and it ended up costing me a few extra slugs of mallory metal in the end.

413 Crank core cost me about $100, but it was part of a package deal.

I've got another 400 block and RB crank at my disposal, so I have been considering pricing out another stroker motor for my next yet to be determined project. I might swing past the machine shop and get a quote for another offset grind.
