440 rods in 400

I always wanted to try that. inwas looking into it years ago and off the shelf piston choices for 383 and 400 at that time sucked. There was a Chevy piston that would have worked with the 383 block, stock stroke, and 440 length rod. Would be interesting, but then that's kind of an expensive "experiment".
I never tried to make power on 87, I wonder how a closed chamber aluminum head with a dished piston designed to match the chamber would work?
