Ok so the Head casting# 3836848, Date code K 30 0, Block casting# 3769925, Date code Con 3 D 20 5 (the 5 could be a 9 it's hard to make out), Ser# F0404LB This engine also has a plate riveted to the block by an comercial engine builder so that may be the origin of the line being installed because there wasn't a hollow bolt in it when I got it. Sooo based on the date codes I don't need the line from the rear bearing or the bolt?
