anyone used a demon carb here? i hear theyre the best of the best.

 

Dont know about that one. I could have got one cheap from the factory not but an hour from me.
My carb guy that custom built my Holly for a supercharger set up told me he knows a few guys that had worked there and a lot of problems go with those carbs.
Pretty much they ignored most of the support calls and the main focus isnt r&d or quality its SELL SELL SELL!
Then again everyone has a story about every manufacture out there. Ive heard very negative things from guys that worked for Edelbrock but i love those intakes. lol

 

I have one on mine Love it no problems at all, simple to set havent had to touch it since install

 

They're good carburetors, but ultimately it's gonna come down to the guy tuning it.

 

is it pretty powerfull? do you think 650s enough for a 351c? oh hey btw where did you buy your 1 piecemontecarlo bar kit

 

my demons run great, they are one of the best bang for the buck carbs out there but they are much more sensitive to changes than holleys and thats where people make the mistake and say they are crap. Demons are rated at avg airflow unlike others which are peak airflow so a demon 650 really flows about 725-735 cfm, I just got my 408 running and am using the 650 speed demon that was on my 351w, I havent touched it and it runs great on a 500+hp engine a 650 should be fine on a 351c but select the carb type, (road demon,speed demon,mighty demon etc...) according to your cam profile if your running a stock cam and a dual plane manifold I would run a 725 road demon. I'm either getting a bigger mighty demon or a pro-systems carb for my stroker. There has been problems in the past with demons but I believe they have fixed it, I hear they have improved the customer service as well. I have ran 3 reman demons off ebay without a problem, I bought one new that had a problem but I fixed it with some jb weld.......they run pretty great right out of the box.

 

awsome thanks for the advice!

i havent really figured out my master intake plane yet but im workin on it and ill def. probably be putting some type of a demon on. i really wanna doa polished tunnel ram with 2 demons on it. ah that would be sweet. but the problem is finding tunnel rams for a 351c.

 

I have had two 650's speed demon and now the mighty demon for my paxton sc. The reman speed demon had to be fixed by BG but it worked great after. I'm placing some AFR's on the motor now so I can't give you a thumbs up on the mighty demon yet.
