What is instinctively? Most car guys do something because someone else gave them some information, be it good info or bad info.
If a Racer says to another racer, "you are not a 'Real Racer' unless your carb has Power Valve Blocks, 'because my race car has "Power Valve blocks". Same deal for a "Hard Core" Racer vs a Normal Racer. I guess you are hard core if you do a lot of stupid chit without knowing what you are really doing. Engine idles at 1200/1300 rpm, rich as can be, have to rev it up over and over to clean that 'bad boy' out.
That is what a race car engine is supposed to be like according to some.
A Power Valve in reality is just another fine tuning device on a carburetor to make each mode of operation closer to the ideal air/fuel vs power curve.
So screw the air/fuel meter and the different circuits on a well designed carburetor (be it from Holley, or Rochester, or Carter originally).
Make that sucker a On-off switch where the only way it will run is at 6000-7000 rpm minimum and most of the time it waters your eyes to be near the car. Because that is what a "hard core" race car engine is supposed to run like.
People actually read this crap.

ps, Many times at the race track the Holley Tech guy put the carb back close to a stock calibration and told the guy, Go make a pass
and if it runs good, leave it alone.

Tom I agree with you 100%! When I was running my super gas , I got talked into removing the power valves. It will make your car run so much better! It did nothing for on track performance! But driving around the pits and the return road, was a different story. It had a huge flat spot ! I hated the way it drove. I ran it two weekends like that before I put the power valves back in.
