Re: Holley 4053 pump shot....Not
How much does the car get driven? Do the float bowls ever go dry? If so then it could still be the diaphram in the booster or the gaskets between the metering plate could be causing a leak down. When you "floor it" the rush of fuel may make it look as though you are getting the full shot, but I'd bet that the shot is leaner than if you were to replace the gaskets and accelerator booster pump diaphram.
If you don't think that this is the probem then try changing to a more aggressive cam for the accelerator booster pump. If you do go with the gaskets I would also check the metering plate and carb body with a straight edge to make sure that the body and/or plate are not warped.
