If you have someone that could turn down the mains to fit a 400 block i would be willing to pay the 700 plus the extra for machine work.

Any competent machine shop should be able to accomplish this job with ease. Unless there is something different on an aftermarket crank. I’ve had a few factory cranks turned down no problem. Kim
