Mild 318 misses at 3000rpm

Got sidetracked yesterday after work. My wife went shopping with my daughter after dinner tonight, so I had some time to head out and set up the new distributor. Got it running right away and this little hot rod teen likes 19* initial with the advance unplugged. With vacuum line connected to dizzy at 600 rpm idle timing advanced to 21*.
Now not wanting to have the neighbors get too pissed at me, I only ran up rpms twice. Happy to report the miss is gone! Thanks to everyone for the help! Looking forward to getting vacuum and timing readings this weekend.
A freak thing happened this past weekend while starting the car, I felt a snap in the throttle. Turns out the pressed end on my Lokar kickdown setup came off on the transmission side. Gotta call Summit and ask them to replace it. It's only two months old.
