I have a VH 253, 4spd, performance manifold, extractors, 600 Holley. After driving for about 25-30 minutes every time she starts choking and cuts out. I have replaced the needle and seat in the carb but no change at all. To get her to fire back up I give the carb a few taps and might get anther 10 mins out of it before it happens again. any ideas?

Sounds very much like the carby needs work.
What work will only become evident when the carby is stripped and cleaned, but very possible gunk is blocking it up.
Power valves can also be a problem with holley carbs

What about the fuel pump?
6 months as well. car was previously ran on straight gas so removed it all and installed 80L vs tank, new fuel pump, fuel filters, performance manifold, and 2nd hand 600 carbie off a mate in great condition who was running it in his VL with no dramas. he only removed it as was selling the car.
