Its all gonna depend on what youre doing to the bottom end,mileage of course is an issue as well,Ive rebuilt probably 4 420a,s,and havent replaced a crank yet.Two of the rebuilds were because #1 rod broke,i replaced the piston/rod assy,re-ringed them all and put the rod bearings back where they were.no problems.If you think you need to do some crank work,you can always send it out have it turned 10/10,and get 10 over bearings,I just dont see replacing a crank unless theres major journal damage as in running an engine without oil,etc.....my .02:D
