Need help on selecting engine bearings

Guys,

Getting ready to dive into an engine product and I was wondering if someone could assist. I am trying to figure out which engine bearings I needfor my build and I am having some trouble. Falicon polished/lightened my crank and they took off the color codes on the crank. Here are my measurements from the crank:
Case bearings 53.03mm for both
rod journals 46mm inside and 49mm outside

any ideas?

I believe the only way to do it correctly is to plastic gauge the crank/bearings and go from there...Always write down the bearing codes first but even then, it can be off .....

Roger at revolution racing may be able to help you...I let another shop build my lower end and it ended up with all but 1 crank bearing measuring over .050 when the max allowed is .038 IIRC.....

Roger KNOWS HIS SHITE..... He has pointed out numerous things during my build process that I have never read, seen nor heard anywhere else.
