I don't want to get into this discussion with all those experts out there . If the crank doesn't turn you 've gotta find out why . The mains should be torqued before the rods go in . The end play should be checked and the real seal installed . did you check your bearing clearances ? I suggest you pull the rods and see if it turns . The seal will offer some resistance . torque mains one at a time . If it binds up STOP something is wrong . If stuck you must find out why before going forward . Each main torqued must not bind the crank . Center the thrust bearing before final torqueing , check end play . If all is good , add one rod at a time and rotate to check for binding . If any rods bind STOP and find out why . Check , check , clean , clean . You may have a bearing on backwards or upside down . Bad clearances , a bent crank lots of things . good luck and don't give up . We're here to help .
