MT Used Demon 650 carb - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**WestButteTruck** · 04-09-2010, 09:28 PM

I have a used Demon 650 with vacuum secondaries that will need a rebuild. I took it off a running 84 with a 350 but I'm not sure the secondaries were working. Electric choke, however it would stick from time to time. Had it hooked to a 700R4 but I'm not sure the linkage was correct. At any rate, I ran it for over a year until I replaced with an edelbrock. AS IS $100 plus the ride. No PM's. I will try and do my best to answer any questions.

SOLD pending payment to FOREVER71, thanks

FOREVER71 · 04-09-2010, 10:31 PM

If forever 71 passes, would you be interested in a trade? PM me if so, because I tend to forget where I post stuff. I have a carter AFB 750 , same as an Edelbrock. I also have several other pieces and parts you might be interested in.

I had to use the Barry Grant website and input some numbers.

http://www.barrygrant.com/demon/imag...tity-Speed.pdf

I have a 6 cast into the top of the body and also the "downleg boosters" which comes out to the 650, VS on the side for vacuum secondary. There wasn't a part number on it anywhere else I could see. I spent some time a while back researching this and am pretty confident in my findings.

FOREVER71, let me know if you are still interested. Is USPO o.k. for shipping?

hey, its weird that all the numbers arent there. im not sure about buying it due to the fact that i bought a 500cfm off ebay already,that was supposed to be a 650cfm. thats why i need the numbers. i dont want to buy a rebuild kit and find out it wont work fo one reason or another.....jeremy

**WestButteTruck** · 04-10-2010, 09:28 PM

Did you check out the web address I posted above? Mine has the number "6" cast into the body, and it has the downleg boosters. Plug in the numbers, you get the 650. I'm convinced. I guarantee or your money back. There, it's in writing. If you don't want it let me know so I can move on to the next person.

EDIT: SOLD to FOREVER71, thanks

FOREVER71 · 04-10-2010, 09:58 PM
