Anyone know if a mafunctioning power valve in a Holley 750 vac sec would cause the engine to stumble and miss at around 3000-3500 rpm with about 1/3 - 1/2 throttle ?? Sounds and acts like its hitting a rev limiter.
Engine will rev past 3500 with no misses with very slight throttle openning so I'm now ruling out ignition. Idles great, runs great on the highway at 3000 with not miss or stumble.
I've replaced: coil, electronic distributor (checked gap), plugs/wires all good, new fuel filter.
Running out of ideas.
Thanks !!
