Demon vs Holley (who do you like best)
depends on what level of carbs we're talking about?
high level drag race carbs the demon has nothing over the holley.
lower level classic dbl pumper holley gives way to the demons smoother designed venturi.
the demon is supposed to mix fuel better as opposed to the entry level holley vac sec/dbl pumpers/chokeless race carbs.
get the same cfm rating as any holley[maybe not any] and you'll find you need less jet=cause it must mix the fuel better.
The other thing are the meter block calibration levels, where holley just sets them the same and doesn't tune for cam duration/profiles.
