    when i tighten up the rod bolts on the rods to 23 ft pounds i cant turn the motor over with a wrench on the crank. it locks up the motor but if i back them off i can.

    Did you use and oil on the bearings when you put it together? Is the head on or off the car? If it is on the car, are your spark plug in? Are your cams timed? It is possible that you are hitting a valve if you have not timed the cams out or if they are not timed correctly.

    You said you replaced the bearings as well... might they be a little to thick?
