what plug did he leave out?

I got my new motor dropped in today. I was feeling pretty good that I saw the missing plug on the right lower part of the block and plugged that. nbd i thought. I dumped the 7 quarts of oil in it and put the priming rod on the drill. when i spin it up i can build 70 psi on the gauge but never build enough resistance in the pump to slow down the drill much..even on 100k junkyard motors it has always stopped the drill at about 70 psi. I know there are a few plugs in the oil passages, im wondering if any of you engine gurus can tell me what one is missing? I know if i read the oiling thread that the answer is there, but really there are 325 posts there. i plan to pull the motor in the am and take it back and can't spend all night reading. HELP!

Thanks in advance guys
