Anyone ever done dyno check Holley vs. Edelbrock?

But the speed demon 850 is only less than 2 hp less than the top dog 905. These are dyno numbers. You put it in a car, on the track, and you may see some different results. The Edelbrocks have a heat soak problem, and they have small float bowls, and the accelerator pump has minimal adjustment. Not desirable on a high performance engine. If you have to keep adjusting a Holley, something is wrong. I have a 750 Demon on my 64 Fury, and a 600 Holley on my Comet, and I can't tell you the last time I had to adjust them.Either you have a dirty fuel system(holleys seem to be very sensitive to this) or you need to study up on how to tune one. One of the recurring statements I hear is "how many turns out should the fuel mixture screws be?" they can be set initially at 1 1/2 to 2 turns out, but they need to be fine tuned with a vacuum gauge or tach, setting them to highest vacuum/rpm, then reset the idle. This after the timing is set.
