Well it had standard bearing in it and the journals looked good so he put sealed power rod bearing "new" and we tq them to 95 as the jim hand book said and we fired it 4 25 min's it sounded killer but a few hard pulls and it was clattering so we took it apart and the bearing looked horrid!i asked him if he used a plasigage he said no it was standard size?so what happen was the crank was scewed from 78 or the bearing or hell i don't know!But it was tight as hell to turn!he said he messed it up so he orded a new crank and matching bearing it will be hear fri scared to have him mess with it now!let ya now when it's back up have a 1000 buck's in it now!!is clevite bearings better than sealed power?later  

No i never use clevite bearing I had problems with them sealed power or speed pro is what I use .
