a "knifed" crank is when they cut material off the counter weights to make then lighter and spin more freely thru the oil/air/whatever they pass thru.....now they shed oil residue off as well. I know Carillo stand by this procedure and are pretty much #1 in the business about doing this to any crank.

Go for forged everything, hey if you can get badass forged H-Beam conrods you oughta be good. Pistons? Hmmmm, Arias? With a slight dome? Would drop compression too much.
Can we have our cylinders sleeved ? I would love to have Darton sleeves....mmm ductile iron
Don't know if there are other block-strengtheners at all, plus we have iron block, should be super strong. Some cylinder sleeve stays?
Dude get the head ported & polished!!
