They "got away from all that" because like you floated around without saying, it effects the corporate guy in his big leather office chair, because you're getting into their pocket by having interchangeably, and serious quality that keeps you from investing in ANOTHER of their products!!!
What a great way to start my day, getting an education on Barry Grant carburetors. Thankyou Jed, I did not know, never messed with one, but next time I go to a swap meet, I will have my eye out for one now. I can honestly say the same about Jegs, have never had a bad experience buying anything from them, they do think about there customers in a positive way. Thanks again for that one.
I had terrible results with the first Barry Grant product I bought, a Speed Demon 750DP. I bought it brand new from the BG tent at a NHRA event, sealed in the box. I put it on my 360 powered Demon street car (3.91 gears, 3000 stall, MP .528" solid lifter cam, J-heads, headers, etc.), replacing a 750 Edelbrock. It was pig rich and never outperformed the old AFB design. I called BG (not Holley at that time) and talked to tech, and they insisted I needed a 650 (I did notice that the Speed Demon's venturi and throttle blades were way bigger than a 4779 Holley) with my "radical" small block (it idled with 15"hg vacuum with the Edelbrock). They said it was really for a big block, so I tried it on my 440 powered Coronet with a MP .509" cam and it was still pig rich!! I fiddled with power valves and the idle feed restrictors, and every sort of adjustment, and never made it run well. Then they came out with that "Idle-Eze" air adjustment under the center stud hole, but I was already burned. SInce then I have bought Street Demons and King Demons with good results. Thanks for the informative video Jed!!
Nothing last better then the old school stuff, I miss having hot rods in the 90s, if it didn't have a holly in it when I bought it, it soon got replaced with one, awesome update on the difference🤘
Got an 750 BG which was on top of my BBC Nova and switched it to a Race Demon with changeable Venturi Sleeves....so I got one of this rare Demons you talking about and still own the BG as an BackUp :)
I remember drilling out the old carbs. It was a pain but sold a lot of metering kits for Holley carbs over the years. Lol. I always liked the adaptability of the old BG carbs.
Scotts Speed Shop I loved the Demon Carb when I first saw them. First one I bought was the 650 Speed Demon. I replaced it with the 750 Mighty Demon. I still run the 750 to this date. One thing you said incorrectly about the bowl sites is the Pre Holley Demons did not have the snap ring to lock them. Mine has the snap rings and I bought mine way way before Holley F'ed them up. I think I bought mine back in 2004 or 2005. I believe Holley changed the fuel bowl inlets too and Holley put their throttle blade lever on the current Demons. I still wish I had the money back then to buy a King Demon with the replaceable venturies . You forgot to mention Demon also was the first to make the carb with the IDLE EZ screw so you don't have to drill hole in the butterflies for more air at idle. I still have the original instruction video somewhere - that was a cheesy video. You can still watch them on TH-cam. Now that the dad of Quick Fuel sold out to Mr Gasket/Holley , I am looking at ATM carbs. The kids of Quick Fuel made ATM and damn these are nice and the price is so good.
Thanks for the additional info and great testimonial to the Barry Grant Demons, if you want a King Demon RS, i have a third one, and don't need it. Email me chargerjezebel70@yahoo.com
I am with you. Carbs work. Some months ago, Drag Boss Garage had a guest on, that had a very interesting story about Mr. Grant and Holley. He may of got back at them, rather well!
know 8 or nine guys who bought Demons, i worked on all of them except 1 that ran exceptionally well. My friend Larry had a 850 demon on his Fox body w/514cube BBF it ran best of 10.62 pump gas street car. I swapped a 9 in stock housing for a box of Holley stuff & built an a 4781 850 double pumper that i did my mods to.I asked him if i could put it on his car because it was very consistant i jetted it 1 size bigger on both ends & it went 10.47's the rest of the night....i built one for him & he sold the Demon...
Awesome 👍🏻👍🏽😀 yeah when I get my old school car it will be a carburetor, I do have a 4 barrel economy which needs rebuilding, but I will probably go for a 2 barrel for cheaper driving with the cost of gas in New Zealand but I will see when I get there
Weber did the same I don't know if they still do but I still have a 45 Weber side draft with 30m chokes wich I ran on an old Harley until I broke it, great carbs as everything is adjustable.
Hey Scott , great video on these carbs ! In the book , Demon Carburetion , on pg 55 , there's a column on the left - King R / S Demons . Does a King Demon like this exist with such small venturii - 1.064 " ( green ) and 1.280 " ( red ) , or is it a misprint ? To have this carb would be awesome for 1:1 throttle linkage in a smaller sgl plane intake ! Thanks and would love to know if any of these are still around .
@MartinOttlyk-xe6yi yes they do exist actually, I've got the one 4150 barry grant, and two king demon RS carbs along with a huge selection of interchangable venturi's, those really small ones take a special base plate if memory serves right, but finding these carbs is tough and finding them at decent prices is even harder. Was gonna run the king demons on a hemi but plans have changed so I'd possibly sell them
Awesome video. I got a Holley Speed Demon sitting around and sorely wish it had those interchangeable venturis. Why did the stop making that system? Who wouldn’t want that ability to change CFM?
What's about the hat it looks as good as any and if it's as significant as you said, noone has a right to say anything about it, great Chanel, All the best to you and your loved ones
I had a few people call me a sellout because I took a deal with Jegs where I can honest reviews on their products. They were talking about all of the stickers, boxes, items, and my hat. So I figured I would let people know I was a fan of Jegs and all of that signage was up long before our deal
@@ScottsSpeedShop no worries it's called progress ,their just jealous, as long as you're onist with people your doing better than most great chanle all the best
Can you mix and match parts to make the ultimate carb you like the adjustable secondaries and the metering blocks from the demon with the interchangeable venturis
I am a BG fan too, right now I'm using a 750VS Screamin' Demon. Apparently most buyers of BG carbs did'nt have the patience to tune them and so they returned them through Summit for example. Those carbs, perfectly okay, went back to BG, now they are used/second hand, only sellable at reduced price. A big loss to BG.
I picked up a BG with the blue sleeves and black metering blocks at a swap meet. It has 175 jets in it, Alcohol I presume. According to the numbers scribed on the main body it should be gas. Any info on this would help me know what I actually have. Are the black metering blocks for alcohol? Thanks
Part number hasn't been in use for atleast 20 years. Unless its in my book, I'll have to check the carb again I know Barry Grants and Demons don't have simple list numbers like holleys. If you want one, the best thing to do is to search Demon carburetor, or barry grant carburetor on ebay, that's all I've done along with Facebook marketplace. I'll see if I can find a rumber. The removable sleeve carbs has RS at the end of their part number, I remember that
Demons are tricky, there should be a number stamped around lip where the air cleaner sits. That single number should be a 6, 7, or 8 if I remember correctly. It's been a while since I've done anything with them
Yeah I speak to him about once every couple of weeks, he is doing fine, just extremely busy as usual. TH-cam is a side thing for him and I, I just so happen to be in the groove to be able to stay on top of producing videos for now. Also he did lose a hard drive which had a ton of video files on it
Are you being specific to the Demon line or just Berry Grant in general..? Havent watched the whole vid yet and maybe this gets explained but i also have heard nothing but negativity about Demon carbs and maybe that is true. The Barry Grant (carb) he is showing us here looks pretty damn trick to me.
@@ScottsSpeedShop I just didnt understand Dennis Richardsons comment and would like him to elaborate or give example to his claim, Maybe like me its all he has ever heard but has had no real experience with them. And yes i am sure they are Jed. Like i said i have never heard anything good about them over the years but the quality is pretty clear on what you have shown here. Thanks for the Vid.
@@SAM-eg7jg most people's bad experiences are based solely on their inability to use an product. Which is precisely why I don't like edelbrock/carter carbs, I am completely inept at doing anything with one and I'll happily admit that
Have ran my old BG Demon 850 for 12 years without a single issue on any combination i have put together.. From running 12.0s to 10.50s it always works and is constant even when there is another issue.... I have ran 16 rounds in competition with every pass being within .02....... Anyone that has a issue with a old demon simply doesn't know how to actually tune one.. There is a reason NHRA banned them from certain class racing..

Even more rare are the Barry Grant inline carburetors. They were a recreation of the Ack Miller inline ford carburetors from back in the 60s
I wish I had bought some.
The carb guy i was really digging this one brother i knew you know All about them and you just proved it great video My friend as always

Have you seen skull garage they are mainly chevy but Justin is excellent in building and tuning carbs .keep up the good work
I've been watching them for a very long time. Since the bad Penny slide show build

In the description it says the part washer can be used as a work bench only after you use it as a parts washer first
Just picked up a demon carburetor with the replaceable Venturi’s today at a swap meet.
