motor lock

i was worndering what could cause the motor to not turn over i just put a timming set on the motor and i could still turn the motor over with no problem with a wrench but after we got it all to geather we saw that now we can turn the motor at all and it was turning fine before i put the power stearing pump and the and the alternater back on

Take em back off and see if you can turn em again. I'm sure you'd hate to take everything apart again.

well i got to looking my dad said it could me that a connecting rod broke but there is a real back chatter when we try to roll it off

I take it you are talking about a timing belt not chain?
Why did you change it?
