Holley vs Demon?
I have a 750 Demon on a 500 HP 427. It seems "sluggish" 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.
