It sounds like a fuel problem, probably either starvation or too rich. If
you were lean, it would knock under that kind of load. You've checked fuel
pressure...is 5 lbs enough...I don't know. The filter appears clean, but it
might be worth swapping in a new $1.99 fuel filter to be sure. I get lots
of microscopic garbage that clogs mine. Carb dashpots full?
Is the exhaust restrictive in any way? Does the car have the original smog
equipment?
Good luck,
Chris
