I would like to hear some opinions on Demon Carbs. Good or bad. I am thinking about using one on my olds 350 build up.

 

I've used a few. I like em.

 

I've heard good things about them from Chevy guys. However, I opted for a Sparky's rebuilt Q-jet for my '69 Olds 350 motor...

 

I have had two diffrent ones and didnt like them,Hard to get a decent tune and didnt seem to hold it when you finally thought you had it......Had to Ebay them both,I thought it was me on the first but after the second one no way...............IMHO you cant go wrong with a Holley..........................Jerr

 

Yup Demon carbs......either you love them, or hate them, from what I have heard.
