hello,

i'm hoping somebody can help me out with a problem that i just came accross (one of the many it seems) i've just finished building my engine a 67 396, hydrolic roller. went to set the rockers and the engine turns smooth until a certain spot then it just stops. it will turn back i don't know how far though because i was told never to turn a engine counter clockwise is that true? i know this could be many things....the problem isn't likely in the bottom end because it was pre assembled by a machinist then assembled by me with an experienced person over looking me do it. it rotated fine when the bottom end was assembled. these are all new parts came as a kit. i'd like to hear some suggestions before i start tearing it down again.....sooooo disapointed, i'm getting nowhere fast with this build lol

thanks
