Holley vs Demon?

[Lynn]

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: TDW</div><div class="ubbcode-body">I have a 750 Demon on a 500 HP 427. It seems &quot;sluggish&quot; on take-off. It is a double pumper. I have been reading about the new Holley Ultra series. The reviews are pretty good. I am wondering if the 4 corner idle is a big improvement over the old style Holley. I have a decent 4780 that I thought about sending to Eric for a freshen up. Anyone have any real world experience with the 3 different carbs? Or even a vacuum secondary Holley? 427, 4 speed, 4.11 gears. 3400 lb Nomad is what I'm playing with. </div></div>

427 4 speed Nomad? I think I see the problem here. That car is REALLY tired of Michigan winters. You need to send it down to Oklahoma with me for about a year (don't forget to send some cash for tires, as I have a feeling those rears are going to need replaced regularly). I promise to take real good care of it (except for those rear tires). Oh, and I have two really nice 780 vac secondary carbs to try out on it. One of them was done by Eric, so it should be perfect!
