I haven't even done the line bore or have the sizes for my bearings yet. After the bottom end is getting balanced iam getting the GE main girdle set which come with arp main studs and getting it lined bored. Then after those are done and I get all my parts back for the bottom end I will start on mearsuing for the correct bearing sizes, plastigague everything and assembly. Then the bottom end should be done. And ready to start on the head work.
