You can do line bore, that is an option, but for the strengh you normaly will cut the crank!
My 440 crank cost me $100 bucks for the 10 / 10 and another $100 to turn down the counters,
rods resized and new bolts $125 bought new OLD set of venolias 60 over, off ebay for $60 bucks they where brand new just never used!!
the 440 steel crank was laying around so made use of it,
so my rotator I'm in cheap!!
