Anybody running a Demon Carb instead of an edelbrock? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just a thought here, but is your edelbrock an electronic choke or manual? I recently unhooked a few wires in my cab to install some BO stuff and I forgot to plug the other stuff back in. My truck ran good, but would not "idle down." It was running at 1000-12000 rpm at idle and about 900 in gear

Not good! I remembered my unplugged wires (one of which was the power lead for the electronic choke). I plugged the wires back in and the idle dropped to 700 and 500 in gear. Much better! Maybe your choke isn't hooked up, getting power, or is not functioning properly?

Just a thought. Good luck with the Demon. I've always wanted to try one out.

Yes, both the Edelbrock & the Demon are electric choke, the Edel idles fine, I'm just tired of monkeying with it to get it dialed in, I figure for $150 for the Road Demon, I can't go rong since their like $400 new. From what I've read about them, I'm sure the performance will be much better, with my truck & the way I drive it, I'm not too concerned about fuel mileage, it's more about how much fun I can have.

I have an 850 speed demon, I called Summit for a rebuild kit and Summit alerted me they have discontinued them...... I call Barry Grant directly and they swear all is good. I like mine but is a race only part, not something I'd try to put around with. I have heard good stuff about the road demons, but it just sounds like you need to tune your edelbrock, atmosphere and altitude effect the carb and if it is rich you need to change the metering rods, H@ul @ss mode is cool, but idle and part throttle are where you spend the majority of your time driving, so tune it. If you don't know how, call Edelbrock, they have a help center that can give ideas as to where to start and the parts, I live in high altitude 5-6,000ft so I call and the tech says, yep you need this, that simple. The edel has been great since, so has the speed demon!

SO? 70RS/SS are you saying stay with the Edelbrock? I figure for $150 for the Road Demon, It'd be kinda fun to try it out, I've heard alot of people say they love em, one guy who went from an edlebrock to the road Demon said it was like night & day the performance was soooo much better with the Demon, I just figured I'd do whater is necessary to the Demon before I install it in the truck.
