400 stroker

Who assembled the motor? You, or the machine shop? Dr side 1-3-5-7. Passenger side all even #. I can't tell where the front of the block is, but the arrows normally point towards the front. They may be numbered incorrectly.
The machine shop put the pistons on the rods. I put the rods on the journals they belong on. I didn't have time to do anything at the moment because I was in the process of moving and I didn't want parts laying in boxes forever. I was a truck driver and wasn't home to do anything about them for a while. Now I am home and have to get this crap straightened out.
