Most misses are ignition related if they occur around the same rpm, but under varying conditions (wot, cruise, decel). Do you by any chance have an msd box? The msd shifts from multiple spark to single spark at around that rpm as the capacitors can not charge fast enough to deliver multiple sparks.
