con= They are the biggest bunch a$$holes you will ever have to deal with. You tell them what is wrong with the carb, and they will tell you there is nothing wrong with it. I have an OLD BG alchy carb, it works flawlessly, but the guy I bought it from said it took 3 tries before BG got it right. As for their new stuff, I think the HP series of carbs from Holley outperforms them, and are about the same money, if not a little cheaper.

Personally, I wouldn't buy anything new from BG. That's why I have all Holley stuff on my car for the fuel system.

I have a friend who worked for several years at my areas largest "speed shop", & he has plenty of stories relating to warranty problems & drivability/performance with the BG carbs.Basically, they are copies of Holley 4150/4500 carbs, with some appearance differances to stay out of court for copyright infringment, where apparently they have been a few years back. Some of their design refinements do look valid, but personally, I have been quite satisfied with the genuine Holley carbs for over 25 years. The 3310-1 780 I have on my 428, I bought back in the late 70`s, it`s been rebuilt several times, & has a welded base plate ear, & primary booster partially melted from a carb fire years ago, but it still works great!

just FYI...I replaced my 700 double pumper with a 775 Race Demon RS and it helped the car out the track and on the street...I love my Race Demon!! I've yet to have a problem with it....

If you want a B flat carb go with the Holley HP series. I hear good things about them from guys I race with. If you want a custom carb built for every last drop of HP you can get. ( I wouldn't unless I was match racing or record setting ) Go to Gary Williams in Jackson, MS. Everyone that races knows who this guy is. Another good bunch is C & S specialties. They will listen to you even if you have one of their carbs from 10 years ago. They keep every build sheet on every carb they've ever done.

I used to be a carb guy.

I own a 850 Mighty demon on my 351C. I got it after I tried my brothers 850 speed demon carb on my car. I used to run a predator carb and I tried a 750 holley double pumper. On the dyno the predator beat the holley 750 by 25hp. I wish I would have had a bigger holley to try out then. I tried the 850 speed demon and I became hooked. I love my 850 M.D. The car has never ran better. As for the tech department here is a copy of a question and a response I got back from them. You make your own opinion on it.

> I now own a 850 Mighty demon carb. I have it on my 351 Cleveland motor in a 1969 Mustang. Runs better then it ever did with my predator carb. Very responsive and no bog. The motor is pushing 480+ horse. My question is on your selection guide. When you say Mild, Moderate and Well prepared. What kind of horse power are we talking about for each selection. What one person might think is Moderate another might think is outrageous.

Tech response:

We do not go by a HP number because that can vary depending on the size of engine, and how it is calibrated. The Mighty Demons are designed for Street Strip cars with cam shaft profiles up to 260 degrees duration @ .050". As for the 850 we normally would not have recommended it for anything less than 480 cubic inches, but if it's running well for you that's great.

Thank you

Great carb for my motor. If someday I get a chance I would like to compare it to a 950HP.

1) Pro Form ANYTHING is junk!
2)You can't beat a Holley.
I just installed an out of the box 4779-9 Holey DP carb on a chebbie yesterday.
Set the floats, adjusted all 4 corners and let her rip.
A bit of a stumble off idle so I replaced the 31 discharge nozzels with 37 long tubes and it's dead nuts perfect. I didn't even have to rejet it yet. 37 degrees of timing and 11.00's out of the box in a 3000 lb 350 CID car!

Ok Ill be the 2nd to praise the Mighty Demon as I dont know about earlier problems but the MD is a beast on my 289.I run the 750 and after seeing mine and riding in it a friend who Vintage races changed his Holley out for one and will never go back.The proof came on the dyno.Better power and air/fuel numbers right out of box. The HP is $120 more in Summit.So if you have to have a Holley be ready to pay for it.But if you cant catch the car in front of you dont be shocked if it has a Demon on top.
