post the complete engine specs and carb model list number and power valve.
stock metering blocks or fubared. ( blocked power valve or....)
the normal range of jetting for a 650 holley with a power valve is 65 to 71 pri and 67 to 78 sec.
A blocked power valve will require 6 to 10 jets bigger. ( a bad idea)
lack of fuel system flow volume @ WOT. a vacuum leak.
how did you arrive at such unusual big jetting? AFR meter, drag strip testing? It feels good.
The details matter.
