RE: hell of a miss) bad spark plug!
hi. what year is car. carb or injection? Misfires can be tricky since everything can cause one. has it misfired ever since you rebuilt it? did it misfire before u rebuilt it? is it just one cylinder? a V8 with one cyl out is noticeable but not too much. i need to know year and fuel delivery first. then ill list some probable causes.

ussually on a fresh rebuild plugs can/will foul out...due to break in....also tune can do it..
the front plugs regardless of design tends to get starved for fuel vs. the back plugs.
i do agree adder.....rotor/caps probably needs to be scraped as well
