Here are the measurements Crank 1) .1906 2) .1906 3) .1894 4) .1907 5) .1907 Block 1) .1914 2) .1911 3) .1924 4) .1921 5) .1928 Which yeild these clearences 1) .0008 2) .0005 3) .0030 4) .0014 5) .0021
Once i get the block back i will measure the mains and figure out what bearings i need to get. One of these day the motor will be in and running.
Oops... epic fail.
So basically #4 is right. I think you've figured out why #1 & 2 were so bad. If I saw these #'s, I'd align bore it. It's okay if #3 is a lil' on the loose side for the crank, but the block seems to be where all the variance is. The reason why I'd align bore it is so I don't have to buy several sets of bearings to piece together a fix for that. You want to be able to replace them with 1 standard set, or one off-sized set if you can.
