With a small base circle cam, a stroker oil pan, clearanced pan rails and rods meant for stroker applications you could do it without too many headaches.

Rod ratio isn't great to begin with, but not horrible. Remember there is lots of thrust stress on a 400 with thin walls, shorter ratios and more power make it worse. I'd definitely use hard-block.

I'd look to see the piston compression height available with what rods.
