Hello! I am rebuilding a 430cid Buick engine and i ran in to a litte problem with bearings. I cant find any markings about size. Supposedly, STD size is correct but i have to make sure before ordering parts to Finland. all the markings i found (hard to read) was GMM400 58043 141V8 And the other half was little more readable: GMM400 58943 141L8 Its my first american V8 so i need a bit of guidance. Thank you in advance.
