What problems would be caused by putting in too much oil (911 83 )?

I replaced the oil from the bottom of the oil tank to the switch in the passenger fender. Then put in oil till the saw some on the dip stick. I thought I wopuld take the car to the car wash and get it warm the check the oil better. About a mile away it started to spit and sputter, like it was out of gas. Looking the rear view I saw a huge white cloud. I checked the oil and it was at the top. I took it home and drained some oil until it was right on dip stick. Now all I have is a car that makes huge smoke clouds. I starts right away and runs (only let run enough to get it in the garage).
