My 69Z has never ran right since restoration. Finally swapped carbs to rule that out, with a different carb (3310) on it and it was a totally different car. Ran like a raped ape. The carb was restored by Holley before I bought the car in mid-restoration. I was told holley put on a new base plate and several other parts of the carb. I have changed the jets to the factory jetting, power valves seem good, nothing seems clogged, shot carb cleaner through every port and orifice.
With the original carb on, the car bogs over 4 grand when driving it, sitting in the driveway it revs as far as I'm willing to go with no breaking up. With a load on it really isn't drivable over half throttle. I plan on checking with Holley to see if they will fix it on their dime, its been several years since it was restored so that may be a trick. If that doesn't work out I will sind it to Eric.
Does anyone have any suggestions before I send it out a second time?
