If you had dual quads would I talk to you out of Holley's...Trust me, I know I'll never talk you out of the Demons, nor am I trying too.

So you're familiar with the new Street Demon carb?..Never liked the Demon carbs. Its mismatch parts.
Im very happy with my 450 twins. Altho i do have twin 660s on the shelf for my boosted build....
Hell id be really surprised if you couldn't find two, 4150, 750 CFM for dirt cheep.
Actually my carbs run very well on the street no hickups no giddy ups.. turn on the fuel pump give a couple Taps and fired right up no problem idles fine...a wideband says all is good and plugs are okay.. just kind of tired of looking at these crusty old mismatched buggers and after 5 years it's time for a change it feels..Two trains of thought on tunnel ram set up.
Wide open and street use...
If you try and tune twins on a tunnel ram for the street its gonna be a long hard dissapointing road...
At some point you just gonna have to say, "thats as good as it gets with out making hard choices."
I'd say it works!
again, not apples to apples comparison. I've got years of Holley experience and history. You have no experience with Demons (nor do I). You need to sharpen your pencil a little with these comparisons, you've not been close.If you had dual quads would I talk to you out of Holley's...
I'll have to grab a link on one of the hot rod write-ups they're very unique for sure..No sir, no experience with their new stuff. Didn't they fold and get bought out by Holley?
Well I've had five years straight with two Edelbrocks and most of the demon carb that were talking about runs on that theory with some thermoquad added to it.. of course on my 72 Duster I put a 600 Holley vacuum secondary and it worked fine. I had to fine-tune the tip in a little bit and get the lighter spring for the secondary but it did well...again, not apples to apples comparison. I've got years of Holley experience and history.

Again the demons that I'm talking about or not the old-style demon the link I just posted was probably the most comprehensive article I've seen on the news Street Demon.. if I'm going to spend the extra 50 or 60 bucks it may be two 750's instead of 625's.....again, not apples to apples comparison.

Well you like to do you're own stuff so buy a powder coat kit and do the carbs and make some side money.I will start with the last thing first and the first thing first.. if yellow rose met me for lunch or agreed to this week I would hold off on buying my carburetors until said conversation was had.. "BUT" (and if I could make that "BUT" as big as the size of the whole entire viewing screen I would!!).. it's been two or three years now and I just don't see it happening and can't put my life on hold till it does...
Now on with the real questions..
As far as my budget I sold an unexpectedly big item on Craigslist the other day and got $400 together like I said and made another hundred today so I have a $500 budget so far.. some more work lined up for the next couple days so I'm thinking I could get two new carburetors.. as far as them running better I would only hope so..
As far as the car and where it is and what it's supposed to do, it's there for my pleasure and happiness...
Correct I have those new heads and they're going to be cool on the car and shiny. I also have my old ProForm electric water pump and my very expensive March performance reduced pulley to run the alternator without a water pump. When I run just two pulleys the large Stock main pulley makes the belt fly off cuz it's too fast without triangulating...
So I'll post my motor and pictures of the parts and you can see that these two old dirty used second-hand carburetors that have done their job for all these years would be out of place with a new set of Speedmaster heads in lieu of the black painted heads I have and the ProForm water pump and March performance pulley in lieu of the stock stuff that I have. And then a couple beautiful Chrome demon Street carbs or whatever yellow rose has this week if him and you can meet me for a cheeseburger to talk me out of or I could just say screw it and get what I them anyways of course.. all while enjoying a big free non fast-food cheeseburger...

^^^now can you see this all together with some direct connection dual quad air filters and a couple blue pentastar medallions on top??..
I'll look at these crusty old carburetors even if I dip them and pull them out extra clean I'd still have to buy rebuild kits and still have two mismatched different brand carburetors...

I got about 6mpg on one on a 351C. Get the street idle XPi (?) version with the idle circuit. I dont see any application for those short of tractor or dyno pulling myself. About as basic of a mixer you can get, maybe 8 moving parts. Near impossible to tune unless you got a machine shop.I haven’t had the chance to run a predator yet, but have talked to a couple of people who have on competition applications. I do intend on trying one in the future, though, however far away that may be.
For discussion sake not arguing with you at all, I'm not! I believe everything you tell me..Just my opinion but those are ugly and if they so good why dose EVERY dyno shop have a Holley 750HP, 850HP and a 950HP jist sitting on their shelf for when a customers engine wont make power?
None of the dyno/ engine tuners i know keep edy carbs on hand.
They will have 4500s also but none have eddy or carter carbs just sitting around?
Before my customer and I went to the machine shop today lol we grabbed my car trailer and put his 65 GTO frame on it and went to the powder coating shop. They have a minimum $25 charge I'm sure they do both carbs for 25 bucks..Well you like to do you're own stuff so buy a powder coat kit and do the carbs and make some side money.

How about if I call the dyno shops and ask them if they've tried the new Street Demon???.. since that's the one that I'm curious about..I say call a few dyno shops, just ask if they have Demon carbs on their shelf/in stock?
