The fact that you have to ask which size bearings is an indicator you are not an experienced engine rebuilder... which is different from removing and replacing parts on the rest of the car.....
The size bearings are not determined until you have taken the rods off the crank throw and put the plastigage on them and retorqued them... then you take it off and carefully inspect how much it was crushed comparing it to the ' guage' on the paper container the plasti-guage came in.
Then you order your proper size bearing.
That Lincoln was not a long stroke inline engine. And it was not a diesel.... where tolerances are much closer than most American made gas engines ever considered being...
But it won't hurt for you to try if you are well versed enough to tell when you have hit a procedure which you can not continue from underneath and do well... that is the point at which you change to normal rules...if you are to not lose your efforts from trying it this way...
